Let the birds on Tree A = x
Birds on Tree B = y
According to question :
When 1 bird fly from tree B to tree A
Trees of A = x + 1
Trees on B = y - 1
x + 1 = y - 1
=> y-x = 2........(i)

When 1 bird fly from tree a to tree b
Birds on Tree A = x - 1
Birds on Tree B = y +1
y + 1 = 2 ( x - 1 )
2x-y = 3............(ii)
From equation (i) and (ii), we get
x= 5 and y = 7.
