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 + 2b = -9b - 4z + 8 for b in terms of z.
| 4\(\frac{1}{2}\)z + 3 | |
| -\(\frac{5}{7}\)z - \(\frac{2}{7}\) | |
| -\(\frac{1}{3}\)z + \(\frac{4}{9}\) | |
| -\(\frac{11}{12}\)z + \(\frac{1}{2}\) |
