They have 146 legs?
Let +c+ = number of cows
Let +h+ = number of hens
given:
(1) +c+%2B+h+=+48+
(2) +4c+%2B+2h+=+146+%7D%7D%0D%0A-------------------%0D%0A%282%29+%7B%7B%7B+2c+%2B+h+=+73+
Subtract (1) from (2)
(2) +2c+%2B+h+=+73+
(1) +-c+-+h+=+-48+
+c+=+25+
and, since
(1) +c+%2B+h+=+48+
(1) +25+%2B+h+=+48+
(1) +h+=+23+
There are 25 cows and 23 hens
check:
(2)
(2) +146+=+146+
OK
