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