Question

In his second basketball game, Jon scored twice as many points as he did in his first
game. In his third game, he scored 4 points less than he did in his second game.
If Jon scored 10 points in his third game, how many points did he score in his first
game?

Answer 1

Let's call the number of points Jon scored in his first game x.
In his second game, Jon scored twice as many points as he did in his first game, so he scored 2x points.
In his third game, Jon scored 4 points less than he did in his second game, so he scored (2x-4) points.
If Jon scored 10 points in his third game, we can set up the equation (2x-4)=10.
Solving this equation, we find 2x=14.
Dividing both sides by 2, we find x=7.
Therefore, Jon scored 7 points in his first game. Answer: \boxed{7}.
