Question

Resolva a inequação:9(3-5)<-4(1-x)

Answer 1

$9(3-5)\ \textless \ -4(1-x) \\ \\ 27-45\ \textless \ -4+4x \\ \\ -18\ \textless \ -4+4x \\ \\ \\ -18+4\ \textless \ 4x \\ \\ 4x\ \textgreater \ -14 \\ \\ x\ \textgreater \ \frac{-14}{4} \\ \\ x\ \textgreater \ - \frac{7}{2}$

S= x>-$\frac{7}{2}$ ou S=(-$\frac{7}{2} ; +\infty$)
