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 = -8b - 8x + 9 for b in terms of x.
| 2\(\frac{3}{5}\)x - 1\(\frac{2}{5}\) | |
| -\(\frac{1}{2}\)x - \(\frac{5}{6}\) | |
| \(\frac{1}{2}\)x + 1 | |
| -\(\frac{7}{10}\)x + \(\frac{9}{10}\) |
