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