=====================================================
Introduction
Linear inequalities are a fundamental concept in mathematics, and solving them is a crucial skill for students to master. In this article, we will focus on solving the inequality . We will break down the solution process into manageable steps and provide a clear explanation of each step. By the end of this article, you will be able to solve linear inequalities with confidence.
Understanding the Inequality
The given inequality is . To solve this inequality, we need to isolate the variable x. The first step is to add 4 to both sides of the inequality, which gives us .
Adding 4 to Both Sides
When we add 4 to both sides of the inequality, we are essentially adding the same value to both sides. This does not change the direction of the inequality, as long as we are adding a positive value. In this case, we are adding 4, which is a positive value.
Isolating the Variable
Now that we have , we need to isolate the variable x. To do this, we can divide both sides of the inequality by -3. However, when we divide both sides of an inequality by a negative value, we need to reverse the direction of the inequality.
Dividing Both Sides by -3
When we divide both sides of the inequality by -3, we get . Note that we have reversed the direction of the inequality, as required.
Checking the Solutions
Now that we have solved the inequality, we need to check the solutions. The solutions to the inequality are all values of x that are greater than -2. We can check this by plugging in values of x that are greater than -2 and verifying that the inequality holds true.
Conclusion
In conclusion, the solutions to the inequality are all values of x that are greater than -2. We can check this by plugging in values of x that are greater than -2 and verifying that the inequality holds true. By following the steps outlined in this article, you can solve linear inequalities with confidence.
