Given: n + 7 + n + 2n - 12 + 3n + 4
Step 1: Rewrite the equation with like terms next to each other
3n + 2n + n + n - 12 + 7 + 4
Step 2: Combine like terms
3n + 2n + n + n = 7n
7 + 4 - 12 = -1
The answer is 7n - 1
+116 n+7+n+2n-12+3n+4 Solve for n? or symplfy?
commutative property of addition states that you can rearrage the problem
n+n+3n+2n-12+7+4
Combine like terms
7n-23 If you were symplying you would stop here.
If not you solve for n
7n-23=0
7n=23
n=23/7
hope this helps!! :D
