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 -9c + 5c = 3c + 6y + 7 for c in terms of y.
| -y - 4 | |
| 7y - 8 | |
| -\(\frac{1}{12}\)y - \(\frac{7}{12}\) | |
| 6y + 8 |
