Given: Let D = the weight of one duck

d = the weight of one duckling

Solve: (3D + 2d = 32)*3 —-> 9D + 6d = 96

(4D + 3d = 44)*2 ——> 8D + 6d = 88

______________

1D + 0d = 8 —–> D = 8

Substitute to solve for d:

4D + 3d = 44

4(8) + 3d = 44

32 + 3d = 44

3d = 12

d = 4

Thus,

2D + d = 2(8) + 4 = 20 kgs.
