Question

# Find the joint equation of the following pair of lines : $$2 x + y = 0 \text { and } 3 x - 5 y = 0$$

Solution

## soln :Eqn of first line $$\Rightarrow 2x+y = 0$$Eqn of second line $$\Rightarrow 3x-5y = 0$$Thus the joint equations of a line is gn by$$(2x+y)(3x-5y) = 0$$$$2x(3x-5y)+y (3x-5y) =0$$$$6x^{2}-10xy + 3xy - 5y^{2} = 0$$$$\therefore 6x^{2}-7xy -5y^{2} = 0$$This is the required joint eqnMaths
