Question

5-2n+n=7 i wanna see if this realy works

Answer 1

I think the answer is n=4. I'm not learning this yet, but here is how I got my answer:

5-2n = 3+n=7

7-3=4n

Hope it helps! :)

Answer 2

5-2n+n=7

Subtract 5 both sides

-2n +n=7-5

-n=2

Divide -1 on both sides

N= 2/-1

Solve

N = -2
