solving polynomial equations

please help 3(n+1)=5(n3) thank you

3(n+1)=5(n3)
3n + 3 = 5n  15
3n  3n + 3 = 5n  3n  15
3 + 15 = 2n  15 + 15
18 = 2n
? = n 
thanks and one more thing 4=c3/61c/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 = (c3)/6  (1c)/8 + c/12 ?
