For the ending don’t you cancel out the x values? The 3x and 10x cancel to be 3 and 10? For number three?

I'm a 17 year old student in Year 12, and im confused about how to solve these types of stuff.
This is easy to understand but the way my teacher teaches us in class is way more complicated.
i can't get which solution i should follow, his or yours, i dont know if it depends on how its solved, or how the question is gonna be made up.
