Question

what solution set makes x in this inequality true?
$-27 + x \geq 15$
a. $x \geq 12$
b. $x \geq 42$
c. $x \geq -42$
d. $x \geq -12$

Explanation:

Step1: Isolate x by adding 27 to both sides

$-27 + x + 27 \geq 15 + 27$

Step2: Simplify both sides of the inequality

$x \geq 42$

Answer:

B. $x \geq 42$
