Question

an equation is shown.
$3(3x - 6)=18$
what is the solution to the equation?
$x = 4$
no solution
$x = - 4$
infinite solutions

Explanation:

Step1: Divide both sides by 3

$\frac{3(3x-6)}{3} = \frac{18}{3}$
$3x - 6 = 6$

Step2: Add 6 to both sides

$3x - 6 + 6 = 6 + 6$
$3x = 12$

Step3: Divide both sides by 3

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

Answer:

$x = 4$
