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 = -7b - 8z + 2 for b in terms of z.
| 3z - 1 | |
| -\(\frac{1}{2}\)z + 3\(\frac{1}{2}\) | |
| -\(\frac{11}{14}\)z + \(\frac{3}{14}\) | |
| \(\frac{1}{7}\)z - \(\frac{6}{7}\) |
