Answer:
See below.
Step-by-step explanation:
2(6 + 3n) - 4 (Given)
12 + 6n - 4 (Distribute)
6n + 8 (Add like terms)
3n + 4 (Divide by a factor of 2)
In case you wanted to solve for n:
2(6 + 3n) - 4 = 0 (Given)
12 + 6n - 4 = 0 (Distribute)
6n + 8 = 0 (Add like terms)
6n = -8 (Substract on both sides)
n = -4/3 (Divide 6 on both sides)
