1) - 2/5 x - 9 < 9/10

Answer 1

$1) \frac{-2}{5} x - 9 \ \textless \ \frac{9}{10} \\ x\ \textgreater \ \frac{99}{10} * \frac{-5}{2} \\ x\ \textgreater \ \frac{-99}{4}$

$2) 4 x + 6 \ \textless \ -6 \\ x\ \textless \ \frac{-12}{4} \\ x\ \textless \ -3$

$3) q + 12 - 2 ( q - 22 ) \ \textgreater \ 0 \\ q + 12 - 2 q +44 \ \textgreater \ 0 \\ -q\ \textgreater \ -56 \\ q\ \textless \ 56$
