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 + 8c = -3c - 2y + 2 for c in terms of y.
| 4y + 2 | |
| 1\(\frac{2}{3}\)y - \(\frac{1}{3}\) | |
| -\(\frac{1}{7}\)y + \(\frac{3}{7}\) | |
| -\(\frac{4}{9}\)y + \(\frac{1}{9}\) |
