When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -5c - 8c = -4c + y + 1 for c in terms of y.
| -7y - 9 | |
| -9y - 1 | |
| -13y + 7 | |
| 3y - 3\(\frac{1}{2}\) |
