Let g be the number of points scored by each girl and b the points scored by each boy.
4g + 2b = 32
4g - 2b = 16
Add the two equations to eliminate 2b
8g = 48
g = 6
Substitute 6 for g in the first equation and solve for b.
24 + 2b = 32
2b = 8
b = 4
Each girl scored 6 points and each boy scored 4 points.
