Question

$\frac{ - 1}{x}= \frac{ - 7}{2}+ \frac{2}{x}$
​

Answer 1

SolutioN :

$\sf \frac{ - 1}{x}= \frac{ - 7}{2}+ \frac{2}{x} \\ \\ \sf= \frac{ - 1}{x} - \frac{2}{x} = \frac{ - 7}{2} \\ \\ \sf = \frac{ - 1 - 2}{x} = \frac{ - 7}{2} \\ \\ \sf = \frac{ - 3}{x} = \frac{ - 7}{2} \\ \\ \sf = x = \frac{ - 7}{2} \times ( - 3) \\ \\ \sf = x = \frac{21}{2}$
