Step-by-step explanation:
Use the distributive formula to solve for n:
-a(b + c) = -ab - ac
So, to solve this you would have to use the distributive property:
-1/3n - 5 = -2
Add 5 to both sides
-1/3n - 5 + 5 = -2 + 5
-1/3n = 3
Now, multiply -3 from both sides
-1/3 * -3 n = 3 * -3
Simplify
n = -9
Hope that helped!!

n= -9
Step-by-step explanation:
-1/3(n+15) = -1/3 * n and -1/3* 15
-1/3*n= -1/3n
-1/3*15= -5
-1/3n -5= -2
Add 5 to both sides
-1/3n = 3
Now divide 3 by -1/3
3/ (-1/3) = -9
n= -9
