3X+2Y=13XY

3X+3Y=15XY ------(1)

3X+2Y=13XY ------(2)

----------

SUBTRACT (1)-(2)

Y=2XY

CANCEL Y ON BOTH SIDES

=> 2X=1

=>X=1/2

FROM EQUATION --(1)

3Y=15XY-3X

3Y=3(5XY-X)

CANCEL 3

Y=5XY-X

=>5XY-Y=X

=>Y(5X-1)=X -----(3)

NOW SUBSTITUTE X IN EQUATION ----(3)

Y(5*(1/2)-1)=1/2

=>Y[(5/2)-1]=1/2

=>Y[2.5-1]=0.5

=>Y[1.5]=0.5

=>Y[3]=1

=>Y=1/3

THEREFORE X=1/2 & Y=1/3
