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 - b = -2b - 5z - 7 for b in terms of z.
| \(\frac{5}{11}\)z - \(\frac{9}{11}\) | |
| -\(\frac{4}{5}\)z - 1\(\frac{2}{5}\) | |
| -\(\frac{3}{8}\)z + 1 | |
| 1\(\frac{1}{4}\)z + \(\frac{3}{4}\) |
