    Lời giải và giải thích chi tiết:
    $10-2.(4-3x)=-4\\\Rightarrow 2.(4-3x)=14\\\Rightarrow 4-3x=7\\\Rightarrow 3x=-3\\\Rightarrow x=-1$
    Vậy $x=-1$.
    $24:(3x-2)=-3\\\Rightarrow 3x-2=-8\\\Rightarrow 3x=-6\\\Rightarrow x=-2$
    Vậy $x=-1$.
    $-45:5.(-3-2x)=3\\\Rightarrow -9.(-3-2x)=3\\\Rightarrow -3 -2x=\dfrac{-1}{3}\\\Rightarrow 2x=\dfrac{-8}{3}\\\Rightarrow x=\dfrac{-4}{3}$
    Vậy x=(-4)/3.
