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 = -3b + 2z - 5 for b in terms of z.
| \(\frac{1}{4}\)z - \(\frac{5}{12}\) | |
| \(\frac{11}{18}\)z - \(\frac{1}{9}\) | |
| -1\(\frac{4}{5}\)z - 1\(\frac{2}{5}\) | |
| 6z + 7 |
