Answer:
y =three point score = 3
x = two point score = 4
Step-by-step explanation:
this question can be solved using simultaneous equation
x + y = 7 eqn 1
2x + 3y = 17 eqn 2
Multiply eqn 1 by 2 to derive eqn 3
2x + 2y = 14 eqn 3
Subtract eqn 3 from 2 :
y = 3
Substitute for y in eqn 1
x + 3 = 7
x = 4
