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 - 2b = -4b + 9z - 6 for b in terms of z.
| 5\(\frac{1}{2}\)z + 4 | |
| \(\frac{2}{17}\)z - \(\frac{9}{17}\) | |
| -\(\frac{2}{3}\)z + \(\frac{2}{3}\) | |
| 3\(\frac{2}{3}\)z - 2 |
