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 + 3z + 3 for a in terms of z.
| \(\frac{5}{9}\)z - \(\frac{1}{3}\) | |
| -13z + 3 | |
| -\(\frac{4}{5}\)z + 1\(\frac{2}{5}\) | |
| -\(\frac{4}{17}\)z - \(\frac{3}{17}\) |
