Asked by breanna
how do i verify a question when i am solving for Y..
yet i need to subsatoute X first to find Y. such as in this probelm to find Y
((xy)/(x+4)-(2y/x)=3 solve for Y
i end up with........lets say that X=4
Y= (3x^2+12x)/(x^2-2x+8)
Y=6
now how am i supposed to verify am i supposed to be getting 3 as my answer and if so how does that work when i have to subsatue X to find Y
