1, 32x5-x=24 2, 2315:(466-x)=5 3, 5xX-2xX=279

`32 xx 5 - x = 24`

`160 - x = 24`

`x = 160 - 24`

`x = 136`

Vậy `x = 136`

_______________________

`2315 : ( 466 - x ) = 5`

`466 - x = 2315 : 5`

`466 - x  = 463`

`x = 466 - 463`

`x = 3`

Vậy `x = 3`

____________________________

`5 xx x - 2 xx x = 279`

`( 5 - 2 ) xx x = 279`

`3 xx x = 279`

`x = 279 : 3`

`x = 93`

Vậy `x = 93`
