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 - 8b = -9b + 6x - 9 for b in terms of x.
| -2x + \(\frac{1}{2}\) | |
| -\(\frac{1}{6}\)x - \(\frac{2}{3}\) | |
| 1\(\frac{3}{4}\)x - 1\(\frac{1}{8}\) | |
| -\(\frac{1}{5}\)x - \(\frac{2}{5}\) |
