Answer 2

Answer:

weight of dog = 17 kg

weight of cat = 7 kg

weight of mouse = 3 kg

weight of all 3 = 27 kg

Explanation:

weight of dog = x

cat = y

mouse = z

y + z = 10

x + z =20

x + y = 24

from 1st: z = 10 - y

put in 2nd: x + 10 -y = 20 ....(4)

from 3rd : x = 24 - y

put in (4): 24 - y + 10 - y = 20

- 2y = 20 - 24 - 10

-2y = -14

y = 7

z = 10 - 7 = 3

x = 20 - z = 20 - 3 = 17
