Solve for n:
12-(n)/(3) = 2
Put each term in 12-(n)/(3) over the common denominator 3: 12-(n)/(3) = 36/3-(n)/3:
36/3-n/3 = 2
36/3-n/3 = (36-n)/3:
(36-n)/3 = 2
Multiply both sides of (36-n)/3 = 2 by 3:
(3 (36-n))/3 = 3×2
(3 (36-n))/3 = 3/3×(36-n) = 36-n:
36-n = 3×2
3×2 = 6:
36-n = 6
Subtract 36 from both sides:
(36-36)-n = 6-36
36-36 = 0:
-n = 6-36
6-36 = -30:
-n = -30
Multiply both sides of -n = -30 by -1:
-n/(-1) = 30
(-1)/(-1) = 1:
Answer: |n = 30
