[ 14 , 17 - X ] x 2/9 = 1/3 

MIK CẦN BÀI NÀY GẤP 

Answer 1

`2/9 - 7/8 x = 1/3`

`7/8 x = 2/9 -1/3`

`7/8x = 2/9 - 3/9`

`7/8x = -1/9`

`x=-1/9:7/8`

`x=-1/9 xx 8/7`

`x=-8/63`

___________________________________

`(14,17-x) . 2/9 = 1/3`

`14,17-x=1/3:2/9`

`14,17-x=1/3 . 9/2`

`14,17-x=3/2`

`14,17-x=1,5`

`x=14,17-1,5`

`x=12,67`

Answer 2

a: =>7/8x=-1/9

=>x=-1/9:7/8=-1/9x8/7=-8/63

b: =>14,17-x=1/3:2/9=1/3x9/2=9/6=3/2

=>x=14,17-1,5=12,67

Answer 3

`2/9 - 7/8 xx x = 1/3` 

`=>  7/8 xx x = 2/9 -1/3`

`=>  7/8 xx x = 2/9-3/9`

`=>  7/8 xx x = -1/9`

`=>x=-1/9 : 7/8`

`=>x=-1/9 xx 8/7`

`=>x=-8/63`

`---------`

`(14 , 17 - x) xx 2/9 = 1/3 `

`=> 14 , 17 - x =1/3 : 2/9`

`=> 14 , 17 - x =1/3 xx 9/2`

`=> 14 , 17 - x = 3/2`

`=>x=14,17-3/2`

`=>x= 12,67`
