4 ( c + 3 ) - ( c - 1 ) = 64?
4c + 12- c +1 = 64
3c +13 = 64
3c= 64-13
3c= 51
c= 17

4c + 12 -c +1 = 64
3c + 13 = 64
3c = 64 - 13
3c = 51
c = 17
To check:
4 (17 + 3) - (17 - 1) = 64
4 (20) - 16 = 64
80 - 16 = 64
64 = 64

You poor thing. School will be over in a few years and you will not have to think about those things. Since I do not have to think of those things, I don't.
