Question I am stuck on this one. The problem is 3.5c-c=630. I am at a lost as where to even start! It would be appreciated if you could explain it simply so it can be understood.
Thank You,

Answer Hello, Amy.
3.5c - c = 630
Since we are solving for 'c,' we need to combine the c factors together. This is because we want the final line to read c = .
3.5c - c = 2.5c. c is the same as 1c, and 3.5 - 1 = 2.5.
2.5c = 630
The final step is to divide both sides by 2.5. Dividing by 2.5 on the left side will leave us with c =, and dividing by 2.5 on the right leaves us with 252.
