Answer:
Infinitely many solutions.
Step-by-step explanation:
2x+y=3
6x=9-3y
-------------
y=3-2x
6x=9-3(3-2x)
6x=9-9+6x
6x=6x
infinitely many solutions
25(2) + 7(1) + 3x = 78....x represents the number of 3 point shots
50 + 7 + 3x = 78
57 + 3x = 78
3x = 78 - 57
3x = 21
x = 21/3
x = 7....so there were 7 three-point shots made
