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 + 5c = -5c + 8y - 5 for c in terms of y.
| 3y - 5 | |
| -\(\frac{1}{10}\)y - \(\frac{1}{5}\) | |
| -1\(\frac{7}{8}\)y + 1\(\frac{1}{8}\) | |
| 9y - 9 |
