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 + 5z - 5 for b in terms of z.
| z + \(\frac{7}{8}\) | |
| 2\(\frac{1}{5}\)z + \(\frac{4}{5}\) | |
| -\(\frac{1}{9}\)z - \(\frac{5}{9}\) | |
| -4\(\frac{1}{2}\)z + 2\(\frac{1}{2}\) |
