Mn giải giúp em với ạ !

Đáp án:

`x=13/12` 

Giải thích các bước giải:

`{(27 5/19- 26 4/13)(3/4+19/59-3/118)}/ {(3/4+x)27/33}={1/13.16+1/14.17}/(1/13.151+ 1/14.16+1/15.17}`

`<=>{(518/19- 342/13)(3/4+19/59-3/118)}/ {(3/4+x)27/33}={1/13.16+1/14.17}/(1/13.151+ 1/14.16+1/15.17}`

`<=>(518/19- 342/13)(3/4+19/59-3/118):(3/4+x)27/33=(1/13.16+1/14.17):(1/13.151+ 1/14.16+1/15.17)`

`<=>236/247.(253/236-3/118):(3/4+x)27/33=223/24752:669/49504 `
`<=>236/247. 247/236:(3/4+x)27/33=223/24752. 49504/669 `

`<=>(236.247)/247.236:(3/4+x)27/33=(223.24752.2)/(24752.223.3)`
`<=>1:(3/4+x)27/33=2/3`
`<=>(3/4+x)27/33=1:2/3`
`<=>(3/4+x)27/33=3/2`
`<=>3/4+x=3/2:27/33`
`<=>3/4+x=3/2. 33/27`
`<=>3/4+x=(3.3.11)/(2.3.3.3)`
`<=>3/4+x=11/(2.3)`
`<=>3/4+x=11/6`
`<=>x=11/6-3/4`
`<=>x=13/12`

Vậy `x=3/2`
