if you know the relation of x and y$,$provide the value of x and the equation value of their relation,how can i use python to caculate the value of y$,$ the conditon of that is not a simple relation of x and y$,$which make you cannot simpify them,only by numerical,for example,r$1=$np$.$sqrt$(($X $+$ mu$)**2+$ Y$**2)$r$2=$ np$.$sqrt$(($X $-(1-$ mu$))**2+$ Y$**2)$U $=-$mu $/$ r$1-(1-$ mu$)/$ r$2-0\mathrm{.}5*($X$**2+$ Y$**2)$now i know the value of X$,$ U$,$ mu$,$how i caculate the value of y
