Question

Các bn làm nhanh lên nhé :))

Answer 1

`-1 5/27-(3x-7/9)^3=-24/27`

`-32/27-(3x-7/9)^3=-24/27`

`(3x-7/9)^3=-8/27`

`(3x-7/9)^3=(-2/3)^3`

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

`3x=1/9`

`x=1/27`

Answer 2

`=>(3x-7/9)^3=-32/27+24/27`

`(3x-7/9)^3=-8/27`

`(3x-7/9)^3=(-2/3)^3`

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

`=>3x=-2/3+7/9`

`=>3x=-1/9`

`=>x=-1/27`
