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 = b - 6z - 9 for b in terms of z.
| -1\(\frac{4}{11}\)z - \(\frac{1}{11}\) | |
| -z + \(\frac{1}{3}\) | |
| -\(\frac{5}{8}\)z - 1\(\frac{1}{8}\) | |
| -z + 3\(\frac{1}{2}\) |
