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 - c = -2c + 5y - 1 for c in terms of y.
| -6y - 9 | |
| y + 2\(\frac{1}{2}\) | |
| \(\frac{3}{5}\)y - \(\frac{1}{10}\) | |
| -\(\frac{2}{5}\)y + 1\(\frac{2}{5}\) |
