Question

2x -1 = (4/2 + 1/4) 6

Answer 1

¡Hola!.

Resolver.

$2x - 1 = ( \frac{4}{2} + \frac{1}{4}) + 6$  <=== amplificamos x2

$2x - 1 = ( \frac{4*2}{2*2} + \frac{1}{4}) + 6$

$2x - 1 = ( \frac{8}{4} + \frac{1}{4}) + 6$

Fracciones homogéneas.

$2x - 1 = ( \frac{8+1}{4}) + 6$

$2x - 1 = \frac{9}{4} + \frac{6}{1}$

$2x - 1 = \frac{9+24}{4}$

$2x - 1 = \frac{33}{4}$

$2x = \frac{33}{4} + 1$

$2x = \frac{33+4}{4}$

$2x = \frac{37}{4}$

$x = \frac{37}{4} / 2$
