Answer
$c=2$
Work Step by Step
The quantity inside of the parenthesis is being multiplied by 2. Thus, we first divide by 2 to find that 8+4c=16. We need to get the c alone. Thus, we cancel out the addition by subtracting 8 on both sides. This leaves us with the equation 4c=8. In order to cancel out multiplication, we use division, so we divide both sides by 4 to get that c=2 We plug 2 in for c and confirm that our answer is, indeed, correct.
