In order for the expression to have infinitely many solutions, we need to have a situation like this:
In other words, we need the left and right hand sides to be the same, so that the equality is actually an identity, and no matter which x-value you choose, the equality will hold.
In your case, if you mimic the template above, you have
And since we want , we want
Let the number of free throws be x and that of point shots be y
x+y=25
⇒x=25-y...i
also:
x+2y=46...ii
substituting i in ii we get:
(25-y)+2y=46
solving for y we get:
y=21
hence
x=25-21=4
thus the number of free shots was 4 and that of point shots was 21
