4y+3x-y> -6+12

can someone give me the answer so i can check if mines right?
(i got:
y> -9/5x+2.4)

Well I don tknow if this is completely true or not but I will explain so I have gotten
y>6+3x over 4 because you combine your 4y with your -y and you get -4y then you add 3x to you r opposite side but on that side you have 6 because you combine the +12 with the -6 and get 6 so then you you divide the 4 on both sides and then 4 dissent got into either number so that is how I got that answer feel free to ask me questions if you don't under stand.
