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 4c + 5c = -2c - 7y - 1 for c in terms of y.
| y - 6 | |
| 1\(\frac{5}{6}\)y - \(\frac{1}{2}\) | |
| -1\(\frac{2}{5}\)y - \(\frac{4}{5}\) | |
| -2y - \(\frac{1}{6}\) |
