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 -3b - 2b = 9b + z - 5 for b in terms of z.
| -\(\frac{1}{4}\)z + \(\frac{5}{12}\) | |
| -\(\frac{1}{6}\)z - \(\frac{5}{6}\) | |
| 1\(\frac{3}{8}\)z - \(\frac{3}{8}\) | |
| -2\(\frac{1}{3}\)z - \(\frac{5}{6}\) |
