question
solve.
4(3x - 3) = 24

Explanation:

Step1: Distribute the 4

$4\times3x - 4\times3=24$, which simplifies to $12x - 12 = 24$.

Step2: Add 12 to both sides

$12x-12 + 12=24 + 12$, resulting in $12x=36$.

Step3: Divide both sides by 12

$\frac{12x}{12}=\frac{36}{12}$, so $x = 3$.

Answer:

$x = 3$
