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 - 3b = -b - 6z - 6 for b in terms of z.
| -1\(\frac{4}{7}\)z + \(\frac{2}{7}\) | |
| -\(\frac{3}{10}\)z - \(\frac{3}{5}\) | |
| 1\(\frac{1}{5}\)z + 1\(\frac{4}{5}\) | |
| 11z - 3 |
