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 = 9b - z - 6 for b in terms of z.
| 1\(\frac{1}{10}\)z + \(\frac{1}{2}\) | |
| -\(\frac{1}{3}\)z + \(\frac{2}{5}\) | |
| -\(\frac{3}{13}\)z - \(\frac{5}{13}\) | |
| \(\frac{7}{9}\)z + \(\frac{8}{9}\) |
