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 6c - c = -9c - 2z - 3 for c in terms of z.
| 7z - 9 | |
| -\(\frac{1}{15}\)z - \(\frac{1}{5}\) | |
| z - 8 | |
| \(\frac{1}{17}\)z + \(\frac{2}{17}\) |
