Question 56869: solve and graph the solution set
3x>7x+20

3x > 7x + 20
This means 0 > 7x - 3x + 20
<-> 0 > 4x + 20
<-> -20 > 4x
<-> -5 > x
You have to look for every x that is smaller then -5.
Try to draw the graph yourself now, it's not that hard.
(hint: draw a vertical line at x=-5 and look to the area on the left of that line)
