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 = 4b - 4z + 4 for b in terms of z.
| -\(\frac{2}{3}\)z - \(\frac{1}{12}\) | |
| 4z - 1\(\frac{1}{3}\) | |
| z - \(\frac{9}{14}\) | |
| -z - \(\frac{1}{2}\) |
