if two bees sir on each flower, one flower will be left do,x=2y(y-1)
or. x-2y+2=0. ----(2)
in graph,(4,3) is the point of intersection. therefore, there are 4bees and 3flowers.
Example-5:
The perimeter ofa resctangular plot is 32m.if the lenght is increased by 2m and the breadth us decreased by 1m, the area if the plit remains the same. Finf the lenght and breadth of the plot.Solution:
Let lenght and breadth if the rectangular land be l and b respectively. then, area=lb. andthen,l+b=16 which implies l+b -16=0 -------(1))
