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