- Step-by-step explanation:
- x+y/xy=2 , x-y/xy=6
- x+y=2xy------1 , x-y=6xy--------2
- x+y/2=xy , x-y/6=xy
- as the rhs is equal we can write the equation as follow
- x+y/2=x-y/6
- 6(x+y)=2(x-y)
- 6x+6y=2x-2y
- 6x-2x= -6y-2y
- 4x= -8y
- x= -8y/4
- x=-2y-----------------3
- substituting equation 3 in equation 1and we get, (-2y)+y=2(-2y)(y)
- -y/y^2=-4
- 1/y=4
- 1/4=y----------4
- substituting 1/4=y in equation 3
- we get, x= -2(1/4)
- x= -1/2
- we get the solutions x= -1/2 ,y= 1/4
