Answer by longjonsilver(2297) (Show Source):
You can put this solution on YOUR website! 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.
