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