Need to solve for c
Find all values of c such that 3*(2c + 1) = 28*(3*c) - 9. If you find more than one value of c, then list your values in increasing order, separated by commas.
Ok, so we can start off by expanding each side:
6c+3=84c-9
Add 9 to both sides:
6c+12=84c
Subtract 6c on both sides:
12=72c
Finally, you can divide 72 on both sides to isolate c:
1/6=c
So the answer I think is just 1/6
