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 + 4b = -3b - x + 9 for b in terms of x.
| -2\(\frac{1}{2}\)x + 4\(\frac{1}{2}\) | |
| -\(\frac{3}{14}\)x - \(\frac{9}{14}\) | |
| 13x - 7 | |
| -6x - 1 |
