Question

-1/3(n + 15) = -2

Explain how to solve it.

Answer 1

Well, BEDMAS contains the answer

Brackets first
We have a variable here so we won’t touch it for now

Multiplication
Cancel the fraction by multiplying by the denominator
-1(n+15) = -6

Divide by -1 to isolate the brackets
N+15 = 6

Add 15 to both sides
N = 21

Double check by putting 21 instead of n into the equation

Answer 2

So for this one you need to distribute -1/3 to n and 15........

-1/3n-5= -2

then to get "n" by itself you need to then add 15 on both sides. 15 will cancel out with -15 (because it becomes 0)...... -1/3n= 3

Then you multiply -3/1 on both sides (you do that to get n by itself (cancellation)), and multiply -3/1 with 3......... n= -9 (ANSWER)
