mathematics

1. If there are x rabbits, there will be (2X+4) chickens.

X+(2X+4)=28

2X+4=20

X=8

A: There are 20 chickens and 8 rabbits.

Second, let a be x and b be y.

X+Y= 12 1

Y=4[Y-(X-Y)] gives x = 77 and y = 44.

A: A is 77 years old and B is 44 years old.

Four to eight species

8 19+334+566+4 17=2 136

8 19+334= 1 153

8 19+566= 1385

8 19+4 17= 1236

334+566+4 17= 13 17

334+566=900
