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 -5c + 3c = -9c - 9y + 8 for c in terms of y.
| -3y + 2 | |
| -1\(\frac{3}{5}\)y - 1\(\frac{4}{5}\) | |
| -\(\frac{1}{3}\)y + \(\frac{1}{18}\) | |
| -3y + 4 |
