Question

$\frac{1}{1} + \frac{3}{2-x} = \frac{1}{2}$

Answer 1

$\dfrac{1}{1} + \dfrac{3}{2-x} = \dfrac{1}{2} \\ \\ \\ \dfrac{2-x + 3}{2-x} = \dfrac{1}{2} \\ \\ \\ \dfrac{x + 5}{2-x} = \dfrac{1}{2} \\ \\ \\ \dfrac{2(x - 5) - x + 2}{2(x- 2)} \\ \\ \\ \dfrac{2x - 10 - x + 2}{2(x- 2)} \\ \\ \\ => \dfrac{x-8}{2x - 4}$
