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 - 7b = b + 2x + 6 for b in terms of x.
| -\(\frac{4}{7}\)x - \(\frac{9}{14}\) | |
| 2x + 2 | |
| 9x + 6 | |
| -x - \(\frac{2}{3}\) |
