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 7b - 9b = 4b - 8z - 2 for b in terms of z.
| \(\frac{1}{3}\)z - \(\frac{2}{3}\) | |
| 1\(\frac{3}{5}\)z + \(\frac{4}{5}\) | |
| 1\(\frac{3}{13}\)z + \(\frac{5}{13}\) | |
| \(\frac{1}{6}\)z + \(\frac{1}{2}\) |
