Anticent math problem how many rabbitsand phesants 35 heads and 94 feet

Answer 1

If all were pheasants, there would be 35 pairs of feet. There are 47 pairs of feet, so there must be 47-35 = 12 rabbits. Each rabbit has one more pair of feet than a pheasant does.

There are 12 rabbits and 23 pheasants.

_____

If you insist on equations, you can let p and r represent the numbers of pheasants and rabbits, then write ...

... p + r = 35

... 2p + 4r = 94

Divide the second equation by 2 and subtract the first:

... (2p +4r)/2 - (p +r) = (94)/2 - (35)

... r = 12 . . . . . . . . . . . simplify

... p + 12 = 35 . . . . . . use the value of r in the first equation

... p = 23 . . . . . . . . . . subtract 12

(p, r) = (23, 12)
