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