Solve the equation (d + 12 = 15) for d, and then substitute the value of D into the expression ( -2(d+8) ) and simplify in order to find your answer.

1) Equation. Use algebraic properties to isolate d on one side.

d + 12 = 15
d + 12 - 12 = 15 - 12
d = 3

2) Expression. Substitute 3 into D and simplify.

-2(d - 8)
-2(3 - 8)
-2(-5)
10

Therefore your answer is 10.
