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