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