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 -4b - b = 5b - 9z + 2 for b in terms of z.
| 1\(\frac{1}{2}\)z - 2\(\frac{1}{4}\) | |
| -\(\frac{7}{12}\)z - \(\frac{1}{3}\) | |
| \(\frac{8}{9}\)z - \(\frac{2}{9}\) | |
| 1\(\frac{2}{5}\)z + \(\frac{2}{5}\) |
