Question

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

2) 4 x + 6 < -6


3) q + 12 - 2 ( q - 22 ) > 0

Answer 1

`1) (-2)/(5) x - 9 \ \textless \ (9)/(10) \\ x\ \textgreater \ (99)/(10) * (-5)/(2) \\ x\ \textgreater \ (-99)/(4)`


`2) 4 x + 6 \ \textless \ -6 \\ x\ \textless \ (-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`
