20 successful shots.
39 points.
Two points - two point shot.
One point - free throw.
Let x = number of two point shots he made, and 20-x = the number of free throws he made.
Now I'll multiply the scoring value (how many points) by the variable, making sure it equals 39.

Substitute x back into your expressions.
Two point shots = x
=19
Free throws = 20-x
=20-19
=1
Test:
# two point shots + # free throws (should) = 20
19 + 1 = 20
Total points should be 39.
19 x two points + 1 x one point
= 19(2) + 1(1)
=38 + 1
=39
Therefore, he made nineteen two-point shots, and one free throw.
