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