The first step is to make the terms each term containing x to be on the left hand side of the equation and the constants to be on the right hand side of the equation. Therefore, we would subtract 9 from the left hand side and the right hand side of the equation.
It becomes
2x + 9 - 9 = 33 - 9
2x = 24
Dividing the left hand side and the right hand side of the equation by 2, it becomes
