Question

10x = 20x + (6x - 2x . 2 - x + (-x)) 

Answer 1

<=> 10x = 20x + ( 6x - 4x - 2x)

<=> 10x = 20x 

=> 10x - 20x = 0

=> 10(x - 2x ) = 0 

=> x - 2x = 0 => x ( 1 - 2 ) = 0

=> x = 0 

Answer 2

tìm x                  

Answer 3

10x=20x+[6x-2x.2-x+(-x)]

10x=20x+(6x-2x.2-x-x)

10x=20x+6x-4x-2x

10x-20x-6x+4x+2x=0

-10x=0

x=0
