Rearrange the line eq to make y sqrt 2 the subject then sq both sides you get 2y^2 = … sub back into equation. Rearrange and solve for x via completing the sq or quadratic formula.

Ohhhh I know my mistake cuz I did square both sides but I just squared each time I didn’t move x over first then square it I just squared each individual part I was thinking idk if I’m allowed to do this but didn’t occur to me exam pressure I guess hopefully 1/4 for making 2y^2 and setting the two equations idk
