Plz help me in the Lesson 6 solve inequalities by adding or subtracting
27.0210002 Math B: sovle inequalites by adding or subtracting plz
To solve inequalities by adding or subtracting, you need to isolate the variable on one side of the inequality sign.
Let's take an example to understand this better:
Example: Solve the inequality 2x - 7 > 11.
Step 1: Add 7 to both sides of the inequality to isolate the variable:
2x - 7 + 7 > 11 + 7
2x > 18
Step 2: Divide both sides of the inequality by 2 to solve for x:
(2x)/2 > 18/2
x > 9
Therefore, the solution to the inequality 2x - 7 > 11 is x > 9.
You can apply this method to any inequality by adding or subtracting to isolate the variable and find the solution.
