if the weight of the rabbit is X
weight of cat Y
weight of dog Z

then the equation below is in order according to the picture

X + Y = 10 (1)
X + Z = 20. (2)
Y + Z = 24. (3)

from equation (1)
X = 10 - Y

from equation (3)
Z = 24 - Y

Substitute the values of X and Z into equation (2)

X + Z = 24
10 - Y + 24 - Y = 20
-2Y + 34 = 20
-2Y = -14
Y = 7
weight of cat = 7

substitute Y into equations (1) and (3)
X + Y = 10
X + 7 = 10
X = 3
weight of rabbit = 3

Y + Z = 24
7 + Z = 24
Z = 24 - 7
Z = 17
weight of dog = 17

total weight = X + Y + Z
=3 + 7 + 17
total weight = 27

ur method is too long... U could hav just used:
20 - x + 24 - x = 10

44 - 2x= 10

2x = 44 - 10

X = 34/2 = 17, weight of dog

> 17 + 10 = 27

I appreciate your opinion.

I also think the above stated solution will be more of an issue to comprehend with, especially with people who are not math-friendly.

Secondly, in as much as the answer to the question was provided, some parameters like the weight of the rabbit and that of the cat were not, this reduces the credibility as to how you arrived at the CORRECT answer.

Thanks
