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 6b - 6b = -8b + z - 4 for b in terms of z.
| \(\frac{2}{3}\)z - \(\frac{2}{3}\) | |
| \(\frac{1}{2}\)z - \(\frac{2}{7}\) | |
| \(\frac{2}{13}\)z - \(\frac{4}{13}\) | |
| 1\(\frac{1}{2}\)z + 4\(\frac{1}{2}\) |
