You can put this solution on YOUR website!
Solve and graph the solution set.
3x%3E=7x%2B20
-7x%2B3x%3E=-7x%2B7x%2B20
-4x%3E=20
-4x%2F-4%3C=20%2F-4 Flip the inequality symbol if you multiply or divide by a negative number.
x%3C=-5
You will shade over the numbers less than -5 (to the left of the numberline) and put either a closed circle or a bracket ] over the -5 (depending on your book or teacher) because of the = part.
