Answer 1

$mathtt{-7leq x textless 4-x;~left{{{xgeq-7}atop{2x textless 4}}right~to~xin[-7;2)}$

$mathtt{-14 textless x+3leq23-4x;~-17 textless xleq20-4x~to~xin(-17;4]}$

$mathtt{7-x textless frac{x-4}{2} textless 9;~18-2x textless x textless 22~to~xin(6;22)}$

$mathtt{x-6leqfrac{x}{5}-2leq3+2x;~-25-5xleq4xleq20~to~xin[-frac{25}{9};5]}$

$mathtt{|x|leq5~to~-5leq x leq5}$  и $mathtt{|y| textgreater 3~to~left[begin{array}{ccc}mathtt{y textless -3}\mathtt{y textgreater 3}end{array}right}$
