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 - 9c = 9c + 4y + 8 for c in terms of y.
| -6y + 3 | |
| -\(\frac{5}{6}\)y - 1\(\frac{1}{6}\) | |
| -y - \(\frac{8}{9}\) | |
| -2\(\frac{3}{5}\)y - 1\(\frac{3}{5}\) |
