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