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
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)
