Question

2/5x-20=10

procedimiento pls?

Answer 1

2/5x - 20 = 10

     2/5x = 10 + 20

    2/5x = 30

       2x = 30(5)

       2x = 150

         x =150/2

         x = 75

eso es todo :D

SALUDOS!!

Answer 2

Respuesta:

x = 4.04

 

Explicación paso a paso:

$\dfrac{2}{5x-20}=10\\\\2=10(5x-20)\\\\2=10*5x-10*20\\\\2=50x-200\\\\2+200=50x\\\\202=50x\\\\x=\dfrac{202}{50}\\\\\boxed{x=4.04}$

 

$\dfrac{2}{5x}-20=10\\\\\dfrac{2}{5x}=10+20\\\\\dfrac{2}{5x}=30\\\\2=30(5x)\\\\2=30*5x\\\\2=150x\\\\x=\dfrac{2}{150}\\\\\boxed{0.013}$
