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 - 3c = 8c + 8y - 9 for c in terms of y.
| \(\frac{1}{4}\)y + \(\frac{5}{8}\) | |
| \(\frac{2}{3}\)y - \(\frac{1}{3}\) | |
| 11y - 9 | |
| -\(\frac{2}{5}\)y + \(\frac{2}{5}\) |
