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 3c - 9c = c - z - 8 for c in terms of z.
| 4z - 4 | |
| \(\frac{1}{2}\)z + \(\frac{1}{14}\) | |
| -\(\frac{1}{2}\)z + \(\frac{3}{5}\) | |
| 1\(\frac{2}{7}\)z - \(\frac{2}{7}\) |
