Answer:

the answer is D.

I actually got the answer by making this equation --->

15+12x= (putting each of the answer choices)

Step-by-step explanation:

Let's solve your equation step-by-step.

15+12x=87

Step 1: Simplify both sides of the equation.

12x+15=87

Step 2: Subtract 15 from both sides.

12x+15−15=87−15

$\frac{12x}{12} =\frac{72}{12}$

x=6
