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 -9c + 3c = -c - 2y - 4 for c in terms of y.
| 1\(\frac{1}{6}\)y - \(\frac{1}{3}\) | |
| \(\frac{1}{11}\)y + \(\frac{9}{11}\) | |
| -1\(\frac{1}{6}\)y + 1\(\frac{1}{6}\) | |
| \(\frac{5}{8}\)y + \(\frac{1}{2}\) |
