-x - 9 [tex] \geq 5[/tex]
You want to get x by itself.
First subtract 9 from both sides of the equation.
-x - 9 [tex] \geq 5[/tex]
+9 +9
-x [tex] \geq 14[/tex]
Then divide -1 on both sides.
-x/-1 [tex] \geq 14/-1[/tex]
I'm pretty sure when you divide a negative number when solving inequalities, you switch the sign.
