Помогите решите этот модуль,побыстрее пож.

1)|x-2| < 4
$\left \{ {x-2\ \textless \ {4} \atop {x-2\ \textless \ {-4} \right.$
$\left \{ {{x\ \textless \ 6} \atop {x\ \textless \ -2}} \right.$
x = (-2; 6)
2)|x+7| < 5
$\left \{ {{x+7\ \textless \ 5} \atop {x+7\ \textless \ -5}} \right.$
$\left \{ {{x\ \textless \ -2} \atop {x\ \textless \ -12}} \right.$
x = (-12; -2)
3) |x+8| < 1
$\left \{ {{x+8 \ \textless \ 1} \atop {x+8 \ \textless \ -1}} \right.$
$\left \{ {{x\ \textless \ -7} \atop {x\ \textless \ -9}} \right.$
x = (-9; -7)
4) |2x - 4|> 2
$\left \{ {{2x-4\ \textgreater \ 2} \atop {2x-4\ \textgreater \ -2}} \right.$
$\left \{ {{2x\ \textgreater \ 6} \atop {2x\ \textgreater \ 2}} \right.$
$\left \{ {{x\ \textgreater \ 3} \atop {x \ \textgreater \ 1}} \right.$
x = (1; 3)
