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 - 4b = 3b + 2z - 9 for b in terms of z.
| -z + \(\frac{1}{7}\) | |
| 1\(\frac{4}{7}\)z + \(\frac{5}{7}\) | |
| -3z + 4\(\frac{1}{2}\) | |
| -\(\frac{1}{6}\)z - \(\frac{5}{6}\) |
