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