Step-by-step explanation:

First what you want to is subtract 7 from both sides, then you want to divide -2/3 from both sides.

To isolate the variable you need to remove the terms from the side with the variable to remove the terms you need to do the same thing on both sides.

-2/3n + 7 = 15

First step is to subtract 7 from both sides to get:

-2/3n = 8

Now divide both sides by -2/3 to get:

N = 8 / -2/3

Then to solve for n simplify to get:

N = -12
