Math Problem Statement

Consider the inequality (-22 - x)/5 - 2 ≥ -7.

Solution

The inequality given is:

22x527\frac{-22 - x}{5} - 2 \geq -7

Step-by-step solution:

  1. Start by isolating the term with the fraction: Add 2 to both sides to eliminate the constant term on the left: 22x57+2\frac{-22 - x}{5} \geq -7 + 2 22x55\frac{-22 - x}{5} \geq -5

  2. Multiply both sides by 5 to eliminate the denominator: 22x5×5-22 - x \geq -5 \times 5 22x25-22 - x \geq -25

  3. Isolate xx: Add 22 to both sides: x25+22-x \geq -25 + 22 x3-x \geq -3

  4. Multiply through by 1-1 to get rid of the negative sign. Remember to reverse the inequality when multiplying by a negative number: x3x \leq 3

Final Solution:

x3x \leq 3

Here are five related questions:

  1. How would the solution change if the inequality were strict (i.e., >> instead of \geq)?
  2. Can you solve this inequality graphically and compare the solution?
  3. What would happen if the inequality involved division by a negative number?
  4. How does solving inequalities differ from solving equalities?
  5. What is the impact of reversing the inequality when multiplying or dividing by negative numbers?

Tip: Always remember to reverse the inequality sign when multiplying or dividing by a negative number in an inequality.
