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 8b + 2b = b - x - 4 for b in terms of x.
| x - \(\frac{1}{3}\) | |
| \(\frac{1}{2}\)x - \(\frac{1}{12}\) | |
| -\(\frac{3}{7}\)x - \(\frac{4}{7}\) | |
| -5x - 2 |
