lochana · Answer

yes. I can show you how it works.

lochana · Answer

first we draw graphs for each inequality.
y = x -1
y = -x+2

lochana · Answer

okay?

lochana · Answer

do you have any questions with that part?

anonymous · Answer

Now, how did you get the plot for x?

lochana · Answer

mm.. you need to find couple of points by putting random x values. then you can draw a line through them at the end.

lochana · Answer

I tell you how to draw graphs after this problem, but can you understand they represent y= x -1 and y = -x +2

lochana · Answer

but make sure that I didn't draw y < x -1 and y> -x +2 .
I just graphed y = x -1 and y = -x +2

anonymous · Answer

Oh okay, so what step would take place  after that?

lochana · Answer

yes. this is the valid points for y < x -1. notice darkened space.
