Thank you.Answer by elima(1433)   (Show Source): You can put this solution on YOUR website!Hi, I hope I can help! 3x>7x+20 First of all you need to get the x on one side, so you subtract 7x form both sides; 3x-7x>7x+20-7x -4x>20 Now divide each side by -4, remember whenever you divide or multiply a negative number you change direction of sign; < x<-5 Now to graph this you will draw a circle around -5 and a solid line to the left covering -6,-7,-8,etc. It's becuase, all those numbers satisfy the equation not including the -5. Hope you understand =)
