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 -6c - 2c = -5c + 4y + 9 for c in terms of y.
| y - 3 | |
| -4y + 1\(\frac{1}{3}\) | |
| -6y - 9 | |
| 11y + 4 |
