⟹ - 6 = \frac{3}{4} - \frac{( - 5) - 2}{f - ( - 5)}⟹−6=43−f−(−5)(−5)−2
⟹ - 6 = \frac{3}{4} - \frac{( -7)}{f + 5}⟹−6=43−f+5(−7)
⟹ - 6 = \frac{3}{4} + \frac{7}{f + 5}⟹−6=43+f+57
⟹ - 6 - \frac{3}{4} = \frac{7}{f + 5}⟹−6−43=f+57
⟹ \frac{ - 24 - 3}{4} = \frac{7}{f + 5}⟹4−24−3=f+57
⟹ - \frac{27}{4} = \frac{7}{f + 5}⟹−427=f+57
⟹ - 27(f + 5) = 28⟹−27(f+5)=28
⟹ - 27f - 135 = 28⟹−27f−135=28
⟹ - 27f = 28 + 135⟹−27f=28+135
⟹ - 27f = 163⟹−27f=163
⟹f = \frac{163}{ - 27}⟹f=−27163
∴f = - \frac{163}{27}f=−27163
