Answer 2

Well since this is just "less than" we will have an open circle...that automatically eliminates 2 answers...

lets solve it

x - 8 < 5x

we want to combine the x's

let's subtract x from both sides

x - 8 < 5x
-x -x

-8 < 4x

now divide both sides by 4

-8 < 4x
-------
4 4

-8/4 < x

-2 < x

or written correctly

x > -2

so we will have an open circle on -2 with shading ....?
