Math Problem Statement

-24< -3x - 3 or -39 > -3x - 3

Solution

You have two inequalities to solve:

  1. 24<3x3-24 < -3x - 3
  2. 39>3x3-39 > -3x - 3

Let's solve each one step-by-step:

Solving the first inequality:

24<3x3-24 < -3x - 3

  1. Add 3 to both sides: 24+3<3x-24 + 3 < -3x 21<3x-21 < -3x

  2. Divide both sides by 3-3 (remember to flip the inequality sign when dividing by a negative number): 213>3x3\frac{-21}{-3} > \frac{-3x}{-3} 7>x7 > x or x<7x < 7

Solving the second inequality:

39>3x3-39 > -3x - 3

  1. Add 3 to both sides: 39+3>3x-39 + 3 > -3x 36>3x-36 > -3x

  2. Divide both sides by 3-3 (again, flip the inequality sign): 363<3x3\frac{-36}{-3} < \frac{-3x}{-3} 12<x12 < x or x>12x > 12

Final Solution:

Combining both results, we have: 12<x<712 < x < 7

This is not possible, as there is no value of xx that satisfies both inequalities at the same time.
