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