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