The point (x,y) lies on both conics x2+xy+x=81 and y2+xy+y=51. Given that x+y is positive, determine the value of x+y.
Top answer:
x ^ 2 + x y + x = 81 x ( x + y + 1 ) = 81 Divide both sides by x x + y + 1 = 81 / x y ^ 2 + x y + y

The point (x,y) lies on both conics x2+xy+x=81 and y2+xy+y=51. Given that x+y is positive, determine the value of x+y.
Top answer:
x^2 + xy + x = 81 xy + y^2 + y = 51 add them to get x^2 + 2xy + y^2 + x + y = 132 (x+y)^2 + (x+y) -

9x^2-4y^2-90x+189=0
Top answer:
9(x^2-10x+25-25)-4y^2+189=0 9(x-5)^2-225-4y^2+189=0 9(x-5)^2-4y^2=36 (x-5)^2/2^2 - y^2/3^2=1
