Let +x+ = the number of geese
+27+-+x+ = the number of horses
+2x+ = the number of feet the geese have
+%28+27+-+x+%29%2A4+ = the number of feet the horses have
----------------------------------
+108+-+4x+%2B+2x+=+78+
+108+-+2x+=+78+
+2x+=+30+
+x+=+15+
and
+27+-+15+=+12+
------------------
There are 15 geese and 12 horses
------------------
check:
geese have
+2x+=+2%2A15+
+2x+=+30+ feet
Horses have:
+78-+30+=+48+ feet
+48%2F4+=+12+
There are 12 horses
OK
