Math Problem Statement

−24≤−3x−3or −39>−3x−3

Solution

We are given the following compound inequality:

243x3or39>3x3-24 \leq -3x - 3 \quad \text{or} \quad -39 > -3x - 3

Step 1: Solve each inequality separately.

For the first inequality:

243x3-24 \leq -3x - 3

  1. Add 3 to both sides: 24+33x-24 + 3 \leq -3x 213x-21 \leq -3x
  2. Divide both sides by -3, and remember to reverse the inequality when dividing by a negative number: 2133x3\frac{-21}{-3} \geq \frac{-3x}{-3} 7x7 \geq x This simplifies to: x7x \leq 7

For 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, and reverse the inequality: 363<3x3\frac{-36}{-3} < \frac{-3x}{-3} 12<x12 < x This simplifies to: x>12x > 12

Step 2: Combine the results.

The solution to the compound inequality is: x7orx>12x \leq 7 \quad \text{or} \quad x > 12

This means the solution set is all values of xx such that:

  • x7x \leq 7, or
  • x>12x > 12.

Final answer:

x7orx>12x \leq 7 \quad \text{or} \quad x > 12
