Can you solve this for x first?

mathlegend · Answer

@almartinez26  'x' should be positive. So what can you divide by to make it positive?

anonymous · Answer

1?

mathlegend · Answer

by -1.

mathlegend · Answer

So once you do that we now have...

x < -3

Because when you divide by a negative... the sign flips...

mathlegend · Answer

This says...

x is less than -3, right?

mathlegend · Answer

Let me ask you... is the symbol pointing to the left or to the right?

anonymous · Answer

mathlegend · Answer

Yes!!
