Given the inequality,
[tex]-2x+9<-27[/tex]To solve the inequality, we first add -9 on both sides.
[tex]\begin{gathered} -2x+9+(-9)<-27+(-9) \\ -2x<-36 \end{gathered}[/tex]Now divide this by - 2.
[tex]\begin{gathered} \frac{-2x}{-2}<\frac{-36}{-2} \\ x<18 \end{gathered}[/tex]Here the mistake made is adding 9 both sides.
Therefore, the answer is x < 18.
