Question

1. what is the solution to the inequality $4x - 1 \leq 11?$

a. $x \leq 3$
b. $x \geq 2.5$
c. $x \leq 2.5$
d. $x \geq 3$

Explanation:

Step1: Add 1 to both sides

$4x - 1 + 1 \leq 11 + 1$
$4x \leq 12$

Step2: Divide by 4 on both sides

$\frac{4x}{4} \leq \frac{12}{4}$
$x \leq 3$

Answer:

a. $x \leq 3$
