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