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 3c - 7c = -8c - 7y + 8 for c in terms of y.
| -y + 2\(\frac{1}{2}\) | |
| y + \(\frac{8}{11}\) | |
| 1\(\frac{2}{5}\)y - 1\(\frac{2}{5}\) | |
| 2\(\frac{1}{4}\)y - \(\frac{3}{4}\) |
