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 = 3b + x - 4 for b in terms of x.
| -11x + 5 | |
| -\(\frac{9}{14}\)x + \(\frac{3}{7}\) | |
| x + 4 | |
| -x - 1\(\frac{2}{5}\) |
