Exercise 19 Page 58

Substitute 3 into the given 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.
- 1>-x/2
\text{-} 1 \stackrel{?}>\text{-}\dfrac{{\color{#0000FF}{3}}}{2}
- 1>-1.5
Since -1 is greater than -1.5, 3 is a solution to the inequality.
