Resposta:

ITEM (C)

Explicação passo-a-passo:

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

$\frac{x - 1}{ - (x - 1)} = \frac{1}{2} + \frac{x}{1 - x}$

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

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

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

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

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

$- 2x = 3(1 - x)$

$- 2x = 3 - 3x$

$- 2x + 3x = 3$

$1x = 3$

$x = \frac{3}{1}$
