Answer 1

Given:

The inequality is,

`-6(x+3)+10<-2`

Step-by-step explanation:

Simplify the inequality for x to determine the mistake.

`\begin{gathered} -6(x+3)+10<-2 \\ -6x-18+10<-2 \\ -6x-8<-2 \\ -6x\cdot(-1)/(6)<6\cdot(-1)/(6) \\ x>-1 \end{gathered}`

When inequality is multiplied with negative number, then inequality sign changes. But Irene did not change the inequality sign after multiplication with negative number. So Irene made mistake from step 4 to step 5.

Answer: From step 4 to step 5
