    Đáp án`+`Giải thích các bước giải`:`

    `(x+0,3)+(x+0,4)+(x+0,5):0,25=(23,4-4,2):(0,75:3)`

    `->x+x+0,3+0,4+(x+0,5) . 4=19,2:0,25`

    `->2xxx+0,7+4 xx x+2=76,8`

    `->2xxx+4xxx+(0,7+2)=76,8`

    `->x xx (2+4)+2,7=76,8`

    `->6 xx x=76,8-2,7=74,1`

    `->x=74,1:6=741/10 xx 1/6`

    `->x=741/60=247/20`

    Vậy `x=247/20`
