Exercise 3 Page 55

Substitute - 6 into the inequality and then simplify.

Yes

Practice makes perfect
We can determine whether 3 is a solution by substituting it into the inequality and simplifying using the order of operations.
c+4<- 1
{\color{#0000FF}{\text{-} 6}} + 4 \stackrel{?}< \text{-} 1
- 2 < - 1
Since - 2 is less than - 1, - 6 is a solution to the given inequality.
