Introduction

In mathematics, inequalities are a fundamental concept that deals with the comparison of two or more values. They are used to represent the relationship between different quantities, and solving inequalities is an essential skill in algebra and other branches of mathematics. In this article, we will focus on solving the inequality 10.6x7-10.6 \geq x - 7, which involves isolating the variable xx and finding its possible values.

Understanding the Inequality

The given inequality is 10.6x7-10.6 \geq x - 7. This means that the value of x7x - 7 is less than or equal to 10.6-10.6. To solve this inequality, we need to isolate the variable xx and find its possible values.

Isolating the Variable

To isolate the variable xx, we need to get rid of the constant term 7-7 that is being subtracted from xx. We can do this by adding 77 to both sides of the inequality. This will give us:

10.6+7x7+7-10.6 + 7 \geq x - 7 + 7

Simplifying the left-hand side, we get:

3.6x-3.6 \geq x

Solving for xx

Now that we have isolated the variable xx, we can solve for its possible values. Since the inequality is of the form x3.6x \leq -3.6, we know that xx is less than or equal to 3.6-3.6. This means that the possible values of xx are all real numbers less than or equal to 3.6-3.6.

Graphical Representation

To visualize the solution to the inequality, we can graph the corresponding equation on a number line. The equation x=3.6x = -3.6 represents a vertical line on the number line, and the inequality x3.6x \leq -3.6 represents all the points to the left of this line.

Conclusion

In conclusion, solving the inequality 10.6x7-10.6 \geq x - 7 involves isolating the variable xx and finding its possible values. By adding 77 to both sides of the inequality, we get 3.6x-3.6 \geq x, which means that xx is less than or equal to 3.6-3.6. This can be represented graphically on a number line, where all the points to the left of the vertical line x=3.6x = -3.6 satisfy the inequality.

Tips and Tricks

  • When solving inequalities, it's essential to remember that the direction of the inequality sign can change when we multiply or divide both sides by a negative number.
  • To solve an inequality, we need to isolate the variable and find its possible values.
  • Graphical representation can be a helpful tool in visualizing the solution to an inequality.

Real-World Applications

Inequalities have numerous real-world applications in fields such as economics, finance, and engineering. For example, in economics, inequalities can be used to model the relationship between supply and demand, while in finance, they can be used to calculate interest rates and investment returns. In engineering, inequalities can be used to design and optimize systems, such as electrical circuits and mechanical systems.

Common Mistakes

  • One common mistake when solving inequalities is to forget to change the direction of the inequality sign when multiplying or dividing both sides by a negative number.
  • Another mistake is to not isolate the variable and find its possible values.
  • Finally, failing to check the solution by plugging it back into the original inequality can lead to incorrect answers.

Introduction

Solving inequalities can be a challenging task, but with practice and patience, you can become proficient in solving them. In this article, we will answer some common questions about solving inequalities, including how to isolate the variable, how to find the possible values of the variable, and how to check the solution.

Q: What is the first step in solving an inequality?

A: The first step in solving an inequality is to isolate the variable. This means getting the variable by itself on one side of the inequality sign.

Q: How do I isolate the variable in an inequality?

A: To isolate the variable, you can add or subtract the same value to both sides of the inequality. For example, if you have the inequality x+35x + 3 \geq 5, you can subtract 33 from both sides to get x2x \geq 2.

Q: What if the inequality has a fraction or a decimal?

A: If the inequality has a fraction or a decimal, you can multiply or divide both sides of the inequality by the same value to eliminate the fraction or decimal. For example, if you have the inequality x23\frac{x}{2} \geq 3, you can multiply both sides by 22 to get x6x \geq 6.

Q: How do I find the possible values of the variable in an inequality?

A: To find the possible values of the variable, you need to determine the values that satisfy the inequality. This can be done by graphing the corresponding equation on a number line or by using a calculator to find the values that satisfy the inequality.

Q: What if the inequality has a negative sign?

A: If the inequality has a negative sign, you need to change the direction of the inequality sign when multiplying or dividing both sides by a negative number. For example, if you have the inequality x2-x \geq 2, you can multiply both sides by 1-1 to get x2x \leq -2.

Q: How do I check the solution to an inequality?

A: To check the solution to an inequality, you need to plug the solution back into the original inequality to make sure it is true. For example, if you have the inequality x2x \geq 2 and you find that x=3x = 3 is a solution, you can plug x=3x = 3 back into the original inequality to get 323 \geq 2, which is true.

Q: What if I make a mistake when solving an inequality?

A: If you make a mistake when solving an inequality, you can try to identify the mistake and correct it. This may involve re-reading the original inequality, re-checking your work, or seeking help from a teacher or tutor.

Q: Can I use a calculator to solve inequalities?

A: Yes, you can use a calculator to solve inequalities. Many calculators have built-in functions for solving inequalities, such as the "solve" function. You can also use a calculator to graph the corresponding equation on a number line or to find the values that satisfy the inequality.

Q: How do I know if I have solved an inequality correctly?

A: To know if you have solved an inequality correctly, you need to check the solution by plugging it back into the original inequality. If the solution is true, then you have solved the inequality correctly.

Q: What if I am unsure about how to solve an inequality?

A: If you are unsure about how to solve an inequality, you can try to break it down into smaller steps, seek help from a teacher or tutor, or use online resources to learn more about solving inequalities.
