Question

no la puere solver la ecuación racional
$\frac{x - 4}{x - 1} = \frac{1 - x}{x + 1}$
​

Answer 1

Respuesta:

X = - 1/2. X = 3

Explicación paso a paso:

(x - 4)(x + 1) = (1 - x) (x - 1)

${x}^{2} - 4x + x - 4 = x - 1 - {x}^{2} + x$

${x}^{2} - 3x - 4 = 2x - 1 - {x}^{2}$

${2x}^{2} - 5x - 3 =0$

2x. 1

X. - 3

(2x + 1)(x - 3) = 0

2x + 1 =0. X - 3=0

2x = - 1. X = 3

X = - 1/2
