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 a - 9a = -4a - 8z - 2 for a in terms of z.
| 1\(\frac{7}{8}\)z + 1 | |
| \(\frac{1}{5}\)z - \(\frac{2}{5}\) | |
| 3z - 6 | |
| -\(\frac{2}{3}\)z + \(\frac{1}{6}\) |
