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 - 9b = 9b - 9z + 5 for b in terms of z.
| z - \(\frac{5}{18}\) | |
| 3z - 4 | |
| -1\(\frac{1}{2}\)z - 1\(\frac{1}{6}\) | |
| -6\(\frac{1}{2}\)z - 1 |
