$c = - 7$ $c=-7$

I would take the $- 4 c$ $-4c$ over the other side of the equals sign and make it positive to give:

$4 c + 20 = - 8$ $4c+20=-8$

You can then subtract 20 from both sides to give;

$4 c = - 20 - 8$ $4c=-20-8$

$4 c = - 28$ $4c=-28$

Divide both sides by four to give:

$c = - 7$ $c=-7$
