Question

ax-1/a+bx-1/b=(2-a-b)x

Answer 1

Respuesta:

Explicación paso a paso:

$ax - \frac{1}{a} + bx - \frac{1}{b} = ( 2 - a ) x$

$ax - \frac{1}{a} + bx - \frac{1}{b } = 2x - ax -bx$

$ax +bx - 2x +ax +bx = \frac{1}{a} + \frac{1}{b}$

$2ax +2bx - 2x = \frac{a + b}{ab}$

$x [ 2 ( a + b -1 ) ] = \frac{( a+b)}{ab}$$x = \frac{( a + b )}{2ab ( a + b -1 )}$

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