Question 4778: x-2y+4<>o
<> I mean is less than equal to, I can't find the button. I do not understand how to do these so if anyone could help me step by step I would greatly appreciate it. Thank you

inequalities are JUST the same as normal equations EXCEPT in 1 situation --> if you multiply or divide by any NEGATIVE number, then the inequality sign swaps round. Now, you could argue that = does the same, but since it is a symmetric symbol, you cannot see the change :-)

So, lets do x-2y+4=0 and x-2y+4<=0 both, so you can see the similarities and differences (if any):

OK, i have actually just read the equation properly...you have an x and a y in it: 2 unknowns but just 1 equation. So you cannot solve this. Please check the question.
