solving polynomial equations

please help 3(n+1)=5(n-3) thank you
3n + 3 = 5n - 15
3n - 3n + 3 = 5n - 3n - 15
3 + 15 = 2n - 15 + 15
18 = 2n
? = n
thanks and one more thing -4=c-3/6-1-c/8+c/12
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 ?
