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