Question

Решите уравнения: а)|х|=4,|х|=0,|х|=-4; б)|х-3|=2,|х-3|=-2

Answer 1

$a)|x|=4=\ \textgreater \ x= \left \{ {{+4} \atop {-4}} \right. \\ b)|x|=0=\ \textgreater \ x=0\\ c)|x|=-4...\\ d)|x-3|=2=\ \textgreater \ \left \{ {{x-3=-2=\ \textgreater \ x=1} \atop {x-3=2=\ \textgreater \ x=5}} \right. \\ e)|x-3|=-2....$
