#### Answer

c=5

#### Work Step by Step

We simplify the expression to: $1/2 = c/2 -2$. We need to get the c alone, so we cancel out the subtraction by adding 2 on both sides. This leaves us with the equation $2.5=c/2$. We cancel out division using multiplication, so we multiply both sides by 2 to get that c=5. We plug 5 in for c and confirm that our answer is, indeed, correct.
