:quad (2x+5y)/(x)=6;(4x-5y)/(x)=-3,x!=0,y!=0

The solution of the system of equations (2x+5y)/(xy)=6" and "(4x-5y)/(xy)+3=6 (where x = 0, y = 0) respectively is ______

2x+3y=5 4x-5y=6

If (3x -4y) : (2x -3y) = (5x -6y) : (4x -5y) , find : x : y .

2x+3y=8 4x-5y=-6

Simplify the following:(x-2y) (y-3x)+(x+y) (x-3y)- (y-3x)(4x-5y).

The figure formed by the lines 2x-5y+4=0, 5x+2y+7=0, 2x-5y+3=0, 5x+2y-6=0 is
