Answer :

Answer:

n = 6

Step-by-step explanation:

We are solving for n in the equation:

4n - 2n + 4 = -1 + 17

First, we can combine like terms:

(4 - 2)n + 4 = 16    ... basically the distributive property:   a(b + c) = ab + ac

2n + 4 = 16

Next, we can subtract 4 from both sides:

2n = 16 - 4

2n = 12

Finally, we can divide both sides by 2:

n = 12 / 2

n = 6
