You can put this solution on YOUR website!

Your goal is to isolate the x.
3x%3E=7x%2B20
-4x%3E=20----when dividing by a negative number, your sign is going to flip directions
x%3C=-5
Your graph would be a number line with a closed dot on -5 and everything shaded to the left.
<----(-6)-----(-5)-----(-4)---->
