    $\frac{x}{5}$ – $\frac{5}{6}$ = $\frac{-19}{30}$

    ⇔ $\frac{x}{5}$ = $\frac{-19}{30}$ + $\frac{5}{6}$

    ⇔ $\frac{x}{5}$ = $\frac{1}{5}$

    ⇔ $x$ = 1

    Vậy $x$ = 1

    Đáp án:

    `x=1`

    Giải thích các bước giải:

    `x/5-5/6=(-19)/30`

    `=>x/5=(-19)/30+5/6`

    `=>x/5=(-19)/30+25/30`

    `=>x/5=6/30`

    `=>x/5=1/5`

    `=>x=1`

    Vậy `x=1`
