Answer:

q ≥
(5)/(7)

Explanation:

Given

- 6q + 7 ≤ 8q - 3 ( add 6q to both sides )

7 ≤ 14q - 3 ( add 3 to both sides )

10 ≤ 14q ( divide both sides by 2 )

5 ≤ 7q ( divide both sides by 7 )


(5)/(7) ≤ q , then

q ≥
(5)/(7)

Explanation:

Step 1: Define

Identify

-6q + 7 ≤ 8q - 3

Step 2: Solve for q

  1. [Subtraction Property of Equality] Subtract 8q on both sides: -14q + 7 ≤ -3
  2. [Subtraction Property of Equality] Subtract 7 on both sides: -14q ≤ -10
  3. [Division Property of Equality] Divide -14 on both sides: q ≥ 5/7

Here we see that any number q greater than or equal to 5/7 would work as a solution to the inequality.
