>>There are 2 trees in a garden (tree "A" and "B") and on the both trees are some birds...<<

Let x = the number of birds on tree "A". Let y = the number of birds on tree "B".

>>If half of birds of tree A come to tree B...<<

Then tree A will have only birds and tree B will have birds.

>>it (tree B) will become equal to the birds on tree A...<<

So which, upon multiplying through by 2, (1) So in the beginning, tree A has twice as many birds as tree B. Remember that as statement (1)

>>and if half of birds of tree B comes to tree A<<

Then tree B will have only birds and tree A will have birds.

it (tree A) will become double of the birds on tree B.

So which, upon multiplying through by 2,
(2) So in the beginning, tree A has one and a half as many birds as tree B. Remember that as statement (2)

>>so, How many birds are on each tree?<<

There is no solution because statements (1) and (2) are contradictory. We solve the system: We substitute 2y for x in 2x=3y 2(2y) = 3y 4y = 3y y = 0 x = 2y = 2(0) = 0 There are no birds on either tree. That can't be a solution unless "some birds" can mean "no birds". Edwin

This problem formulation is   H E A V I L Y   /  F A T A L L Y     W R O N G.

It is clear just from its first phrase / sentence, and there is NO any need to read it further.

Good only to throw it into a GARBAGE BOX.
