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 = -5c - 4y + 4 for c in terms of y.
| -y + \(\frac{4}{9}\) | |
| -17y - 3 | |
| -\(\frac{5}{9}\)y - \(\frac{1}{18}\) | |
| 2\(\frac{1}{6}\)y + \(\frac{1}{2}\) |
