$c=70$
We need to get the c alone. Thus, we cancel out the addition by subtracting 9 on both sides. This leaves us with the equation $-14=c/-5.$ In order to cancel out division, we use multiplication, so we multiply both sides by -5 to get that $c=70$. We plug 70 in for c and confirm that our answer is, indeed, correct.
