Solve.

−3(n + 8) = 15

the solution is n =

.

First, we can do distributive property.

-3(n + 8) = 15

-3 x n = -3n, -3 x 8 = -24 

So we have, -3n + -24 = 15
 
Minus -24 on both sides of the equal sign.

-3n + -24 - -24 = 15 - -24 

-3n = 39

Divide 3 on both sides.

-3n/-3 = 39/-3

n = -13

Hope i helped!! :D

-3(n + 8) = 15
-3n - 24 = 15
-3n = 15 + 24
-3n = 39
n = 39/-3
n = -13
