Exercise 16 Page 58

Substitute -3 into the given inequality and then simplify.

No

Practice makes perfect
We can determine whether -3 is a solution by substituting it into the inequality and simplifying using the order of operations.
5-x<8
5-({\color{#0000FF}{\text{-} 3}}) \stackrel{?}< 8
8≮ 8
Since 8 is not less than 8, - 3 is not a solution to the inequality.
