Steps for solving:
1. First you want to simplify the left side by distributing the 7 through both of your terms inside the set of parentheses.
2. This leaves us with 7c + 28 - 19 = -26
3. We can simplify one step further on the left side
by subtracting 28 - 19 to get 9.
4. So we have 7c + 9 = -26.
5. Now subtract 5 from both sides to get 7c = -35.
6. Finish things off by dividing both sides by 7 and we find that c = -5
