tolong donk gimana?sama carnya yak please

[tex] \frac{ \frac{ {x}^{2} + {y}^{2} }{x + y} }{ \frac{x}{y} + \frac{y}{x} } \\ = \frac{ {x}^{2} + {y}^{2} }{ x + y} \div ( \frac{x}{y} + \frac{y}{x} ) \\ = \frac{ {x}^{2} + {y}^{2} }{xy} \\ = \frac{ {x}^{2} + {y}^{2} }{x + y} \div \frac{ {x}^{2} + {y}^{2} }{xy} \\ = \frac{ {x}^{2} + y}{x + y} \times \frac{xy}{ {x}^{2} + y} \\ = \frac{xy}{x + y} [/tex]
