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 5b + b = 2b + z - 4 for b in terms of z.
| 6z + 8 | |
| -\(\frac{11}{14}\)z + \(\frac{1}{2}\) | |
| z - \(\frac{1}{2}\) | |
| z - 1\(\frac{1}{3}\) |
