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 = -5b + 9z - 9 for b in terms of z.
| -\(\frac{2}{5}\)z - \(\frac{3}{5}\) | |
| \(\frac{4}{7}\)z - \(\frac{9}{14}\) | |
| -\(\frac{1}{12}\)z + \(\frac{7}{12}\) | |
| \(\frac{1}{5}\)z - \(\frac{1}{2}\) |
