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 -4b - b = 8b - 4z - 9 for b in terms of z.
| 10z - 6 | |
| \(\frac{3}{17}\)z + \(\frac{6}{17}\) | |
| 2\(\frac{1}{5}\)z + \(\frac{2}{5}\) | |
| \(\frac{1}{4}\)z + \(\frac{3}{4}\) |
