All you have to do is add the like terms.
(They are all like terms, so just add everything)
4c + 2c + c
6c + c
= 7c
Now we know that
7c = 266
We need to isolate c in 7c, to do that we will eliminate 7.
Eliminate it by dividing 7.
7c ÷ 7 =
[property of equality - also divide 7 on the other side since you are making changes to this side]
7c ÷ 7 = 266 ÷ 7
c = 38 [final answer]
