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