9-70.

Evaluate the inequality $x+4<2x-3$ for the following values of $x$. Decide if the given value of $x$ makes the statement true or false. Show all of your work.

Substitute each value for $x$ in the inequality given above.

1. $x=4$

$\mathbf{4}+4<2(\mathbf{4})-3$

Simplifying, you get:
$8<8-3\\ 8<5$
Is $8$ less than $5$?

False

1. $x=-2$

$\mathbf{-2}+4<2(\mathbf{-2})-3$

Simplifying, you get:
$2<-4-3\\ 2<-7$
Is $2$ less than $-7$?

1. $x=7$
