cat=10-rabbit ....(i)
dog =20-rabbit .....(ii)
dog+cat=24 ......(iii)
adding equation (i) &(ii)
cat+dog=10+20-2rabbit
from equation (iii)
24=10+20-2rabbit
2rabbit=30-24
rabbit=6/2
rabbit=3
therefore cat+rabbit=10
cat+3=10
cat=7
cat+dog=24
7+dog=24
dog=17
dog +cat+rabbit=17+7+3=27
dog =20-rabbit .....(ii)
dog+cat=24 ......(iii)
