How to find a element in elliptic curve ?(code added)
$Q=G*x$
$Q_2=G_2*y$
$G_2 = Q[n]=G[t]$
$Q=Q2$
$Q$, $G$, $G_2$ are points on elliptic curve.
$x$, $y$ are big integers.
$Q$, $Q_2$, $G$, $G_2$, $y$ are known.
How to find x ?
P.s. help me please. I'm very need help.

# This section after x was find. Find x and paste to this code:

Could you please provide the code to construct
Q, G, G_2, y?I will provide code for construct Q, G, G_2, y shortly. Thank you for your answer Tmonteil !!!Tmonteil I hope for your future help. Br !
HELP ME PLLEEEEASE FIND X ???? PLEEEASSSEE
HELP ME PLEASE ???
Please format sage / python code as code. For this, just indent all the code in some editor with 4 spaces or copy+paste it here, mark it, and while having it marked hit that button with the
101and010on it. As it is, the question is not readable. It would be also a good idea to describe the objects you have first, then the "needed $x$" with given properties. Could you please edit the question to have a readable text?
