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 + b = -9b + 2z - 4 for b in terms of z.
| \(\frac{3}{4}\)z + 1\(\frac{3}{4}\) | |
| \(\frac{1}{18}\)z - \(\frac{2}{9}\) | |
| -\(\frac{1}{5}\)z - \(\frac{4}{5}\) | |
| \(\frac{1}{2}\)z + \(\frac{1}{10}\) |
