    Giải thích các bước giải:

    $-5-(3-2x)=1+x$

    $-5-3+2x=1+x$

    $2x-1+x=(-5)-3$

    $2x-1+x=-8$

    $x.(2-1)=-8$

    $x.1=-8$

    $x=(-8):1$

    $x=-8$

    `-5-(3-2x)=1+x `
    `=> -5 -3 + 2x = 1+x`

    `=> -8 + 2x = 1+x`
    `=> -8 + 2x – 1 – x =0`
    `=> x – 9 =0`
    `=> x =9`
    Vậy `x=9`
