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 - 8c = -7c + 9y + 8 for c in terms of y.
| 1\(\frac{4}{7}\)y - \(\frac{2}{7}\) | |
| -\(\frac{4}{9}\)y - \(\frac{1}{18}\) | |
| 1\(\frac{6}{11}\)y + \(\frac{8}{11}\) | |
| 4\(\frac{1}{2}\)y - 4\(\frac{1}{2}\) |
