Question

What is the answer to this equation? -30n = -27n - 63

Answer 1

`-30n=-27n-63\ \ \ \ |+27n\\\\-3n=-63\ \ \ \ |:(-3)\\\\n=21`

Answer 2

you want to get the ns together so add 27n to -27n to eliminate it from the right side and add it to -30n. so youre equation would be

-3n=-63

and then to isolate n and get ur answer you divide -3 by -3n and -3 by -63 so.

n=21 would be ur answer.

hope it helps!
