Hello there i hope you are having a good day :) Your question : x-2y=0 ,x²+xy+y²=27 ? Answer : Firstly you would find the variable in one of the equations, then Takeaway the result into the other equation. So this would be
(1 - √
433 /4) - (1 - √433/8) Then X would be (1 - √
433 /4) and Y would be (1 - √433/8) Then you would add them (1 + √433/4) and (1 + √433/8) Same as before as X and .
Hopefully that helps ya ❤
