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 8a - a = -9a - z - 5 for a in terms of z.
| z + \(\frac{2}{11}\) | |
| 5z - \(\frac{1}{2}\) | |
| z - \(\frac{5}{17}\) | |
| -\(\frac{2}{13}\)z - \(\frac{6}{13}\) |
