c=-324

Explanation:

First, get all the variables on one side of the equation and everything else on the other side. In this case, you subtract 5 from both sides to get c/9=-36.

Then solve for c by multiplying both sides by 9 and get c=-324.

Now to check your work, you can plug -324 in for c and that will equal the right side, -31:
5+(-324)/9=-31
