Let B= Booker's score in game 1

B=7 points

Let H1=Hooker's score in game 1

Let H2=Hooker's score in game 2

Game 1: H1=B+21

Game 2: H2=14 + H1 = 14+B+21

B+B+14 = 28

2B = 28-14= 14

B = 14/2 = 7 for game 1

B+14 = 7+14 = 21 for game 2

H1 = 7+21 = 28 which is 21 more than B's 7 points

H2=14+28=42 which is 21 more points than B's 21 points
