Answer 1

$Resolu\c{c}\~ao\to \left\{\begin{array}{ccc} \frac{3}{x} + 5= \frac{1}{2} \\\\ \frac{3+5x}{x} = \frac{1}{2}\\\\x = 6+10x\\\\9x = -6\\\\\boxed{\boxed{x = - \frac{6}{9} =- \frac{2}{3} }} \end{array}\right$

Espero ter ajudado. :))

Answer 2

$\frac{3}{x} + 5 = \frac{1}{2} \Leftrightarrow \frac{3}{x} = \frac{1}{2} - 5 \Leftrightarrow \frac{3}{x} = -\frac{9}{2} \Leftrightarrow 3 = \frac{-9}{2} x \Leftrightarrow \frac{3.2}{-9} = x \Leftrightarrowx = \frac{-2}{3}$
