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