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 b - 8b = -3b - 9z - 5 for b in terms of z.
| -3z + 6 | |
| z - \(\frac{1}{3}\) | |
| -\(\frac{2}{13}\)z + \(\frac{6}{13}\) | |
| -\(\frac{1}{4}\)z - 1\(\frac{1}{4}\) |
