28 = -4(n + 15)

OpenStudy (anonymous):

Divide both sides by -4 first.

OpenStudy (anonymous):

Then subtract both sides by 15. And that's it. (Be aware: when you divide the left side by a negative, it will become negative. THUS, when you subtract 15 from both sides, the left side will become MORE negative, not positive)
