Giải hộ mình vs vote 5 sao cộng 1 tim

Đáp án+Giải thích các bước giải`:`

`1)270:[51-(2*x-7)]=3^3`

`51-(2*x-7)=270:3^3`

`51-(2*x-7)=270:27`

`51-(2*x-7)=10`

`2x-7=51-10`

`2x-7=41`

`2x=48`

`x=48:2`

`x=24`

Vậy `x=24`

`2)720:[41-(2*x-5)]=2^3*5`

`720:[41-(2x-5)]=40`

`41-(2x-5)=18`

`2x-5=23`

`2x=23+5`

`2x=28`

`x=14`

Vậy `x=14`

`3)2448:[119-(x-6)]=24`

`119-x+6=2448:24`

`125-x=102`

`x=23`

Vậy `x=23`

`4)1045:[215-(3*x-24)]=5`

`215-(3x-24)=1045:5`

`215-(3x-24)=209`

`3x-24=215-209`

`3x-24=6`

`3x=30`

`x=10`

Vậy `x=10`
