$\frac{6d}{d - e} - \frac{6e}{d + e} = \frac{6d(d + e) - 6e(d - e)}{(d + e)(d + e)} = \frac{6 {d}^{2} + 6de - 6de + 6e {}^{2} }{d {}^{2} - e {}^{2} } = \frac{ 6d {}^{2} + 6e {}^{2} }{d {}^{2} - e {}^{2} }$

$\frac{6 - wx}{6w + wx} + \frac{6x}{6 + x} = \frac{6 - wx + 6wx}{w(6 + x)} = \frac{6 + 5wx}{6w + wx}$

$e - \frac{ {e}^{2} }{e + 5} = \frac{e(e + 5 )- e {}^{2} }{e + 5} = \frac{ {e}^{2} + 5e - {e}^{2} }{e + 5} = \frac{5e}{e + 5}$
