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