Isolate the n variable
...
39 + 9 + 9n - 39 - 9 = 111 - 39 - 9
9n = 111 - 3 - 9
9n = 99
Divide both sides by 9
9n%2F9+=+99%2F9
highlight_green%28n=11%29

39%2B9%2B9n=111 Start with the given equation.


9n%2B48=111 Combine like terms on the left side.


9n=111-48 Subtract 48 from both sides.


9n=63 Combine like terms on the right side.


n=%2863%29%2F%289%29 Divide both sides by 9 to isolate n.


n=7 Reduce.
