Math Problem Statement

x−5<−11 or x−1≥−5 Solve the inequality for x

Solution

To solve the compound inequality x5<11x - 5 < -11 or x15x - 1 \geq -5, we will solve each part separately.

1. Solve x5<11x - 5 < -11:

x5<11x - 5 < -11 Add 5 to both sides: x<11+5x < -11 + 5 x<6x < -6

2. Solve x15x - 1 \geq -5:

x15x - 1 \geq -5 Add 1 to both sides: x5+1x \geq -5 + 1 x4x \geq -4

3. Combine the solutions:

The solution to the compound inequality is the union of the two individual solutions: x<6orx4x < -6 \quad \text{or} \quad x \geq -4

So, the solution for xx is x<6x < -6 or x4x \geq -4.

  4. Solve the compound inequality: 4x314x - 3 \leq 1 or x+2>10x + 2 > 10.
  5. Solve the inequality: 2x+5>92x + 5 > 9 or x62x - 6 \leq -2.

Tip: When solving compound inequalities, remember that "or" means you combine the solutions from each part, while "and" means you take the intersection of the solutions.
