In mathematics, inequalities are a fundamental concept that plays a crucial role in solving various problems. In this article, we will focus on solving six different types of inequalities, covering basic algebraic manipulations and more complex fractional inequalities. We will break down each inequality into manageable steps, making it easier for readers to understand and apply the concepts.

1. Solving the Inequality: $-3x - 1 \geq 41 - x$

To solve the inequality $-3x - 1 \geq 41 - x$, we need to isolate the variable $x$ on one side of the inequality sign. The first step is to add $x$ to both sides of the inequality, which gives us:

$$-3x + x - 1 \geq 41 - x + x$$

Simplifying the left-hand side, we get:

$$-2x - 1 \geq 41$$

Next, we add $1$ to both sides of the inequality to get:

$$-2x \geq 42$$

Now, we divide both sides of the inequality by $-2$, remembering to reverse the direction of the inequality sign when dividing by a negative number:

$$x \leq -21$$

Therefore, the solution to the inequality $-3x - 1 \geq 41 - x$ is $x \leq -21$.

2. Solving the Inequality: $\frac{x}{2} + 11 \leq 13 - x$

To solve the inequality $\frac{x}{2} + 11 \leq 13 - x$, we need to isolate the variable $x$ on one side of the inequality sign. The first step is to add $x$ to both sides of the inequality, which gives us:

$$\frac{x}{2} + x + 11 \leq 13 - x + x$$

Simplifying the left-hand side, we get:

$$\frac{x}{2} + x \leq 13$$

Next, we subtract $\frac{x}{2}$ from both sides of the inequality to get:

$$x \leq 13 - \frac{x}{2}$$

Now, we multiply both sides of the inequality by $2$ to get rid of the fraction:

$$2x \leq 26 - x$$

Next, we add $x$ to both sides of the inequality to get:

$$3x \leq 26$$

Finally, we divide both sides of the inequality by $3$ to get:

$$x \leq \frac{26}{3}$$

Therefore, the solution to the inequality $\frac{x}{2} + 11 \leq 13 - x$ is $x \leq \frac{26}{3}$.

3. Solving the Inequality: $\frac{x}{10} - 6 \ \textless \ -7$

To solve the inequality $\frac{x}{10} - 6 \ \textless \ -7$, we need to isolate the variable $x$ on one side of the inequality sign. The first step is to add $6$ to both sides of the inequality, which gives us:

$$\frac{x}{10} - 6 + 6 \ \textless \ -7 + 6$$

Simplifying the left-hand side, we get:

$$\frac{x}{10} \ \textless \ -1$$

Next, we multiply both sides of the inequality by $10$ to get rid of the fraction:

$$x \ \textless \ -10$$

Therefore, the solution to the inequality $\frac{x}{10} - 6 \ \textless \ -7$ is $x \ \textless \ -10$.

4. Solving the Inequality: $6x + 2 \geq 62$

To solve the inequality $6x + 2 \geq 62$, we need to isolate the variable $x$ on one side of the inequality sign. The first step is to subtract $2$ from both sides of the inequality, which gives us:

$$6x + 2 - 2 \geq 62 - 2$$

Simplifying the left-hand side, we get:

$$6x \geq 60$$

Next, we divide both sides of the inequality by $6$ to get:

$$x \geq 10$$

Therefore, the solution to the inequality $6x + 2 \geq 62$ is $x \geq 10$.

Key Takeaways

• To solve an inequality, we need to isolate the variable on one side of the inequality sign.
• When adding or subtracting the same value from both sides of an inequality, the direction of the inequality sign remains the same.
• When multiplying or dividing both sides of an inequality by a negative number, the direction of the inequality sign is reversed.
• To solve a fractional inequality, we need to get rid of the fraction by multiplying both sides of the inequality by the denominator.

Final Thoughts

In the previous article, we covered the basics of solving inequalities, including algebraic manipulations and fractional inequalities. However, we know that there are many more questions and concerns that readers may have. In this article, we will address some of the most frequently asked questions about solving inequalities.

Q: What is the difference between an inequality and an equation?

A: An inequality is a statement that two expressions are not equal, while an equation is a statement that two expressions are equal. Inequalities are often denoted by symbols such as $\geq$, $\leq$, $>$, or $<$.

Q: How do I know which direction to flip the inequality sign when multiplying or dividing both sides by a negative number?

A: When multiplying or dividing both sides of an inequality by a negative number, you need to flip the direction of the inequality sign. For example, if you have the inequality $x \geq 5$ and you multiply both sides by $-2$, the resulting inequality would be $-2x \leq -10$.

Q: Can I add or subtract the same value from both sides of an inequality?

A: Yes, you can add or subtract the same value from both sides of an inequality. This is a fundamental property of inequalities, and it allows you to isolate the variable on one side of the inequality sign.

Q: How do I solve a fractional inequality?

A: To solve a fractional inequality, you need to get rid of the fraction by multiplying both sides of the inequality by the denominator. For example, if you have the inequality $\frac{x}{2} \geq 3$, you can multiply both sides by $2$ to get $x \geq 6$.

Q: Can I use the same steps to solve a system of inequalities as I would to solve a system of equations?

A: No, you cannot use the same steps to solve a system of inequalities as you would to solve a system of equations. Inequalities have different properties and require different techniques to solve.

Q: How do I graph an inequality on a number line?

A: To graph an inequality on a number line, you need to plot a point on the number line that represents the solution to the inequality. For example, if you have the inequality $x \geq 3$, you would plot a point at $x = 3$ and shade the region to the right of the point.

Q: Can I use a calculator to solve an inequality?

A: Yes, you can use a calculator to solve an inequality. However, you need to be careful when using a calculator to solve an inequality, as it may not always give you the correct solution.
