Answer:
There are 25 reindeers and 17 snowbirds
Step-by-step explanation:
A reindeer has 4 legs while a snowbird has two legs
Let the number of reindeer be x while the number of snowbirds is y
Total heads is 42;
x + y = 42 •••••••(i)
let’s now count the legs
4(x) + 2(y) = 134
4x + 2y = 134 ••••••(ii)
divide ii by 2
2x + y = 67
y = 67 - 2x
and from i above too, y = 42-x
equate the y
67-2x = 42-x
67-42 = -x + 2x
x = 25
y = 42-x
y = 42-25
y = 17
