Question

Ada yg bisa bantu?? pakai cara

Answer 1

(a/x) + (b/y) = 1 |x a| (a^2/x) + (ab/y) = a
(b/x) + (a/y) = 1 |x b| (b^2/x) + (ab/y) = b
----------------------------------------------------- -
................................... (a^2 - b^2)/x = (a - b)
................................... (a^2 - b^2)/(a - b) = x
x = (a + b)(a - b)/(a - b) = a + b
