8c=5c+21 What would that be

NemiM [27]

To solve for C, you have to get both of the numbers with a C on the same side. So, subtract the 5c from the right side onto the left side.

$8c = 5c + 21\\8c - 5c = 5c - 5c + 21\\3c = 21$

Then, divide by 3 on each side.

$3c = 21\\3c /3 = 21/3\\c = 7$

So, c = 7.
