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