Question

Решений системы неравенств x< 3 4-x> 0

Answer 1

$\left \{ {{x\ \textless \ 3} \atop {4-x\ \textgreater \ 0}} \right. \\\\ \left \{ {{x\ \textless \ 3} \atop {-x\ \textgreater \ -4}} \right. \\\\ \left \{ {{x\ \textless \ 3} \atop {x\ \textless \ 4}} \right. \\$
Т.е. решением будет x∈(-∞, 3)
