Answer:
N = 4
Step-by-step explanation:
In the equation 2n + 7 = 15, we have to isolate the variable. But, before that, we have to get rid of anything else. Like the +7 in the equation. So we can subtract from each side.
2n + 7 = 15
Take out the +7 by subtracting 7 on both sides.
2n + 7 - 7 = 15 - 7
2n = 8
Now, to get rid of the 2 next to the n, we have to divide both sides by 2
2n/2 = 8/2
n=4
