Dear Student,

Let the weight of one duck and one duckling be 'x' kgs and 'y' kgs, respectively
Then, according to question,3x + 2y = 32                 
 (i)4x + 3y = 44                 
 (ii)We have to find the value of 2x + y
Multiplying equation (i) by 2, we get:6x + 4y = 64                  
 (iii)Subtracting equation (ii) from equation (iii), we get:      6x + 4y =   64      4x + 3y =   44(-)    (-)       (-)________________      2x +   y =   20Thus, the weight of two ducks and one duckling is 20kg
