Question

ayuda,con solución porfavor xdddd​

Answer 1

$\frac{a}{b} - \frac{a {}^{2} }{bx} + \frac{b}{a} - \frac{ {b}^{2} }{ax} = 1 \\ \frac{a {}^{2} + {b}^{2} }{ab} = 1 + \frac{ {a}^{3} + b {}^{3} }{ab {x} } \\ {a}^{2} + {b}^{2} = ab + \frac{a {}^{3} + {b}^{3} }{x} \\ a {}^{2} - ab + b {}^{2} = \frac{(a + b)(a {}^{2} - ab + {b}^{2}) }{x} \\ 1 = \frac{(a + b)}{x} \\ x = a + b$
