HEY ....
LOOK ....
LET, NO. OF HENS = X
AND NO. OF COWS = Y...
EACH ANIMAL HAS 1 HEAD SO....
THE EQN WILL BE ....
X + Y = 59
X= 59-Y
HENS HAVE 2 FEET AND COWS HAVE 4 FEET .....
SO THE EQN WILL BE....
2X+4Y= 190
= X+ 2Y= 95....
now PUT X= 59-Y IN THIS EQN....
(59-Y)+2Y= 95
59+Y= 95
Y= 95-59...
Y=36....
so no. of cows is 36....
plz mark as brainliest......☺❤

Cows = x
Hens = y
x + y = 59
4x + 2y = 190 2x + y = 95
x = 95 - 59 = 36
