Question

Tell whether c= -2 is a solution of the inequality: -4c ≥ 7

Answer 1

Answer: Yes it's a solution

We can check it by replacing c with -2 and simplifying

-4c ≥ 7

-4(-2) ≥ 7

8 ≥ 7

The last statement is true, so the original statement is true when c = -2. Therefore, c = -2 is a solution.
