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 9b - b = 4b - 8z + 2 for b in terms of z.
| -1\(\frac{2}{5}\)z + \(\frac{2}{5}\) | |
| 4z - 3 | |
| 1\(\frac{1}{2}\)z - 2\(\frac{1}{2}\) | |
| -\(\frac{5}{13}\)z - \(\frac{6}{13}\) |
