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 = -6c + y - 4 for c in terms of y.
| -\(\frac{1}{3}\)y - \(\frac{4}{15}\) | |
| -\(\frac{1}{5}\)y + \(\frac{4}{5}\) | |
| \(\frac{1}{2}\)y - \(\frac{9}{14}\) | |
| -11y + 9 |
