Math Problem Statement

Solve for x.

−8x+10>−22

Solution

To solve the inequality 8x+10>22-8x + 10 > -22, follow these steps:

  1. Subtract 10 from both sides of the inequality: 8x+1010>2210-8x + 10 - 10 > -22 - 10 Simplifying: 8x>32-8x > -32

  2. Divide both sides by 8-8. Remember, when you divide by a negative number, the inequality sign flips: x<328x < \frac{-32}{-8} Simplifying: x<4x < 4

Thus, the solution is x<4x < 4.
