Question 876356: Solve the inequality, and then graph its solution:
6x – 5 – 3x > 14 – 5x – 3
so far I understand I have to get x alone right?
I don't know how to put the number line but I got x>2
I just equaled both equations together and followed the order of operations and got that I'm not sure I did it right
