Solve the inequality for x: -5(x + 5) + 26 ≤ 2(8 - x). Simplify your answer as much as possible.

Solution

To solve the inequality:

5(x+5)+262(8x)-5(x + 5) + 26 \leq 2(8 - x)

Step-by-Step Solution:

  1. Distribute the terms within the parentheses: 5(x+5)=5x25-5(x + 5) = -5x - 25 2(8x)=162x2(8 - x) = 16 - 2x

    Substituting these into the inequality, we get: 5x25+26162x-5x - 25 + 26 \leq 16 - 2x

  2. Combine like terms on the left side: 5x+1162x-5x + 1 \leq 16 - 2x

  3. Move all terms involving xx to one side and constants to the other side:

    • Add 2x2x to both sides: 5x+2x+116-5x + 2x + 1 \leq 16 3x+116-3x + 1 \leq 16

    • Subtract 1 from both sides: 3x15-3x \leq 15

  4. Divide by -3 and reverse the inequality sign (since dividing by a negative number reverses the inequality): x5x \geq -5

Final Answer:

x5x \geq -5

Here are some additional questions related to this topic:

  1. How would you solve a similar inequality if there were absolute values involved?
  2. What would change if the inequality symbol were << instead of \leq?
  3. How would the solution change if there were no negative signs on the variable terms?
  4. Can you graph the solution x5x \geq -5 on a number line?
  5. What is the impact of multiplying or dividing both sides by zero in an inequality?

Tip: Always remember to reverse the inequality sign when you multiply or divide by a negative number in inequalities.
