# I have an elliptic curve y^2=x^3+1. I want to add the point P(2,3) and to a multiple of thepoint Q(x,y). Such that in my results, the highest power of y is 1. Let's say I want to compute P+4Q [closed]

Points on elliptic Curve, given one specific point and another a general point

This was essentially answered in your previous question: https://ask.sagemath.org/question/74204/ Here the curve just a bit different, but the same approach applies.
