The point (x, y) in the plane for which 6x + 6y = 5xy and 6y - 6x = xy is
Given, equation of planes is
6x + 6y = 5xy .......(1)
6y - 6x = xy .........(2)
Solving equation (1) + equation (2)
12y = 6xy
$$\Rightarrow$$Β 12y - 6xy = 0
$$\Rightarrow$$Β 6y(2-x) = 0
$$\Rightarrow$$Β y = 0 or 2-x = 0
$$\Rightarrow$$Β y = 0 or x = 2
From equation (1)
When y = 0, 6x + 0 = 0 $$\Rightarrow$$ x = 0
When x = 2, 6(2) + 6y = 5(2)yΒ $$\Rightarrow$$ y = 3
$$\therefore\ $$Required point is (2,3)
