यदि `xlt0,ylt0,x+y+(x)/(y)=(1)/(2)` और `(x+y)(x)/(y)=-(1)/(2)` हो, तो x=……….. व y=………..

(xy)/(x-y)=(1)/(2);(xy)/(x+y)=(1)/(5) wherex +y!=0;x-y!=0

Fill in the blanks If x<0,y<0,x+y+(x/y)=(1/2) and (x+y)(x/y)=-(1/2), then x=( and y)/( and y)

If y!=0 then the number of values of the pair "(x,y)" such that x+y+(x)/(v)=(1)/(2) and " (x+y)(x)/(y)=-(1)/(2) is

If xlt0,ylt0" such that "xy=1," then "tan^(-1)(x)+tan^(-1)(y)=..........

(2x -2y+3) dx -(x-y+1) dy=0 , " when" x=0, y=1

if y=(1)/(2)sin^(-1)((2xy)/(x^(2)+y^(2))) and y

Centre of the circle (x - x_(1)) (x-x_(2)) + (y-y_(1)) (y- y_(2)) = 0 is
