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 b + 2b = 9b - x - 3 for b in terms of x.
| \(\frac{3}{8}\)x + \(\frac{3}{8}\) | |
| x - 6 | |
| -x + \(\frac{2}{3}\) | |
| -2x + \(\frac{2}{5}\) |
