3(n+1)=5(n-3)

3n + 3 = 5n - 15

3n - 3n + 3 = 5n - 3n - 15

3 + 15 = 2n - 15 + 15

18 = 2n

? = n

You need to show where parentheses go in that last equation. Even though they may not be in your printed assignment, you need them here when typing equations on a single line, without spaces.

Do you mean

-4 = (c-3)/6 - (1-c)/8 + c/12 ?
