Question

`50%x +2/3x=x+4`

Answer 1

`1/2x + 2/3 x = x + 4`

`7/6x = x + 4`

`1/6x = 4`

`=> x = 24`

Answer 2

=>1/2+2/3x-x=4

=>1/6x=4

hay x=24

Answer 3

`50%x +2/3x=x+4`

`<=>50/100x + 2/3x = x+4`

`<=> 1/2x + 2/3x = x+4`

`<=> (1/2+2/3)x=x+4`

`<=> ( 3/6 + 4/6)x=x+4`

`<=> 7/6x=x+4`

`<=> (7x)/6=x+4`

`<=>7x=6x+4`

`<=> x=24`

Answer 4

`50%x + 2/3 x=x+4`

`<=> 3/6x + 4/6x = x+4`

`<=> 7/6x -x-4 =0`

`<=> 7/6x -6/6x =4`

`<=> 1/6x= 4`

`=> x =4:1/6 =4*6 = 24`

Vậy `x=24`
