Beth has hamster s at her house.the number of hamsters is equal to the sum of the number of birds at Kristin's house and the number of dogs at Wendi s
house. John has the same number of cats as Wendi has dogs. If these four children have a total of 12 pets how many pets are at each house. PLEAS EXPLAIN!!!!!

This one is a bit horid isn't it.
I think the question should have stated more clearly that each child only has one type of pet. Anyway,
I am going to try to :)
1) Beth has hamster s at her house.the number of hamsters is equal to the sum of the number of birds at Kristin's house and the number of dogs at Wendi s house.

This is made to sound more complicated than it realy is because each child only has one type of pet and thew are all different from one another so you can just talk about
hamsters, birds, cats and dogs. So lets simplify the question.
1) The number of hamsters is equal to the number of birds + the number of dogs.
2) Number of cats = number of dogs.
Let the number of cats be x, then number of dogs is x too
Let the number of birds be y
then the number of hamsters is x+y
so altogether we have x+x+y+(x+y) pets and this equals 12 pets.
x+x+y+(x+y) =12
3x+2y=12
x and y have to both be more than 0 and whole numbers
If x is 1 y is 4.5 which is not a whole number
If x=2 then y would be 3
If x=3 y =1.5 which is not a whole number
If x=4 then 0 and that is too little
So x=2 and y=3
So there are 2 cats and 2 dogs and 3 birds and 2+3=5 hamsters.
Just like our guest found. :)
Total is 12 Hamsters is 'x' x = kbirds + wdogs jcats=wdogs
12 = x + (kbirds + wdogs) + jcats
Substituting
12 = x + (kbirds +wdogs) + jcats
12 = (kbirds + wdogs) + (kbirds+wdogs) + wdogs
12 =2kbirds + 3wdogs
Since we can only have whole numbers of animals, the only solution here is
kbirds = 3 wdogs =2 so x= hamsters= kbirds + wdogs = 5 jcats= wdogs = 2
