You can put this solution on YOUR website! We want to have all n's on one side and all numbers on the other side.
What ever we do to one side, we should do to to both sides.
add n to both sides
n+n-20=8
add 20 to both sides
n+n=28
combine n's
2n=28
We still want all numbers on one side
divide by 2 (both sides)
n=14
