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 9b - 9b = -9b + 5z - 3 for b in terms of z.
| \(\frac{7}{9}\)z - \(\frac{1}{6}\) | |
| 1\(\frac{1}{6}\)z + \(\frac{5}{12}\) | |
| 2\(\frac{3}{4}\)z + \(\frac{3}{4}\) | |
| -\(\frac{9}{11}\)z + \(\frac{3}{11}\) |
