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 + 6c = c - 5y - 2 for c in terms of y.
| 4y + 6 | |
| -y - \(\frac{1}{6}\) | |
| y + \(\frac{1}{4}\) | |
| 1\(\frac{1}{10}\)y + \(\frac{1}{5}\) |
