If x² + xy = 62, y2 + xy = 82 then find the positive value of x+y.
A) 11 B) 12
C) 13 D) 14

answer;B) 12explanation:::

after adding both equation

we \: get..

{x}^{2} + xy + {y}^{2} + xy = 62 + 82 x^2 + y^2 + 2xy = 144 (x + y)^2 = 144 (x + y) = sqrt{144} x + y = 12it may be helpful for u❤❤❤plzzz mar it as a brilliant ans
