Now imagine that if Y equal to 0; Y equal to 0 means x equal to y Y is we have defined x minus y if Y equal to 0 then x equal to y, then this equation this equation x equal to y y equal to 0 naturally this equation will not be there. this now this it this converted to a single equation only this equation.
पहिल्या प्रकारात जर Y=0 असेल तर Y=x-y असल्यामुळे x=y मिळेल आणि एकच समीकरण मिळेल.
