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 - 2c = 3c - 2y + 7 for c in terms of y.
| -13y - 5 | |
| -\(\frac{1}{3}\)y + 1\(\frac{1}{6}\) | |
| y + 1\(\frac{1}{6}\) | |
| 3\(\frac{1}{2}\)y + 3 |
