Đáp án+ Giải thích các bước giải:
$ĐK:2x+4≥0=>2x≥-4=>x≥-2$
$\\|x-3|=2x+4$ $\\<=>\left[ \begin{array}{l}x-3=2x+4\\x-3=-2x-4\end{array} \right.$ $\\<=>\left[ \begin{array}{l}x-2x=4+3\\x+2x=-4+3\end{array} \right.$ $\\<=>\left[ \begin{array}{l}x=-7\\3x=-1\end{array} \right.$ $\\<=>\left[ \begin{array}{l}x=-7(KTM)\\x=-\dfrac13(TM)\end{array} \right.$
