Question

solving multiple step equations
solve the equation below:
$15(x + 3) = 60$
○ $x=1$ (marked)
○ $x=-3$
○ $x=1$
○ $x=5$

Explanation:

Step1: Divide both sides by 15

$\frac{15(x+3)}{15} = \frac{60}{15}$
Simplify to get: $x + 3 = 4$

Step2: Subtract 3 from both sides

$x + 3 - 3 = 4 - 3$

Answer:

C. X=1
