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