Set the number of chickens as x and number of cows as <span>y
</span>so the farmer has total 28 animals
so x+y=28
you know that since the animals are healthy
chickens will have 2 legs and
cows will have 4 legs
the total number of legs are 64
so 2x+4y=64
since you want to find the number of cows
so from the first equation <span>x+y=28
</span>we will get another equation <span>x=28-y
</span>then plug into <span>2x+4y=64
2(28-y)+4y=64
56-2y+4y=64
56+2y=64
-56 -56
2y=8
y=4
</span>

You can ignore any information that is not about the weekend or what time he wakes up in the morning. The only information we care about in this problem is that perry wakes up at 7:30 on Saturday and 8:00 on Sunday. This would make his average time 7:45am
Solution:
we are given that
Three people are comparing their ages.
Let charlie age be x , ann's ages be y and bob age be z , then we can write using the given info
charlie and ann's ages add to 5 years more than bob's age.
Now using the given info. that charlie and bob's ages add to 6 years more than twice ann's age.
Again using -ann and bob's ages add to 7 years more than four times charlie's age.
Now we will solve these three equations together using calculator we get
x=34, y=57 and z=86
Hence charlie age is 34 , ann's ages is 57 and bob age is 86.
