" If "x-y=(x+y)/(2)=(xy)/(4)" the "xy

Q. 11 The solution of (dy)/(dx)=(2x-y+3)/(x+2y+4) is y^(2)-x^(2)+xy+4y-3x+1=C x^(2)-y^(2)+xy+4y+3x-1=C y^(2)-x^(2)-xy-4y+3x-1=C y^(2)-x^(2)+xy+4y-3x-1=C

x-x^(2)y+xy^(2)-y

The quotient of x by y added to the product of x and y is written as (x)/(y)+xy(b)(y)/(x)+xy(c)(xy+x)/(y) (d) (xy+y)/(x)

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

Solve the simultaneous equations : (6x+3y)/(xy) = 6, (2x+4y)/(xy) = 5

If xy = ae ^(x) + be^(-x) then xy _(2) + 2y _(1) - xy =

Solve: (x+y)/(xy)=2 and (x-y)/(xy)=6

The average of the reciprocals of x and y is (a) ((x+y))/((x-y)) (b) ((x+y))/(2xy) (c) (2(x+y))/(xy) (d) (2xy)/((x+y))
