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 = b - 2z + 4 for b in terms of z.
| -\(\frac{4}{7}\)z + 1\(\frac{2}{7}\) | |
| \(\frac{4}{5}\)z + \(\frac{4}{5}\) | |
| \(\frac{3}{4}\)z - 2\(\frac{1}{4}\) | |
| -12z - 5 |
