Let's define the next variables
x: field goals made
y: kick after touchdown made
Rodrigo has made 62 total kicks, then:
x + y = 62 (eq. 1)
Rodrigo has made 116 points, then:
3x + y = 116 (eq. 2)
Subtracting equation 1 to equation 2,
3x + y = 116
-
x + y = 62
--------------------
2x = 54
x = 54/2
x = 27
Replacing into equation 1,
27 + y = 62
y = 62 - 27
y = 35
Then, he made 27 FG's and 35 PAT's
