Math Problem Statement

5x−2>−42or

5x−2<43

Solution

We are given two inequalities to solve for xx:

  1. 5x2>425x - 2 > -42
  2. 5x2<435x - 2 < 43

Solving the first inequality:

5x2>425x - 2 > -42 Add 2 to both sides: 5x>405x > -40 Now, divide both sides by 5: x>8x > -8

Solving the second inequality:

5x2<435x - 2 < 43 Add 2 to both sides: 5x<455x < 45 Now, divide both sides by 5: x<9x < 9

Combined result:

The solution is: 8<x<9-8 < x < 9 This means xx is greater than 8-8 and less than 99.

Tip:

When solving inequalities, remember that multiplying or dividing by a negative number reverses the inequality sign.
