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 - 4b = -2b + 9z - 8 for b in terms of z.
| \(\frac{1}{13}\)z + \(\frac{4}{13}\) | |
| 2\(\frac{1}{6}\)z - 1\(\frac{1}{3}\) | |
| 2\(\frac{1}{2}\)z + 3\(\frac{1}{2}\) | |
| -1\(\frac{1}{12}\)z - \(\frac{5}{12}\) |
