Respuesta :

So your goal is to isolate x.

The first thing you do is add 100 to both sides to cancel the -100 out.

You are left with 14x<240

Then you divide both sides by 14 to isolate your variable and cancel out the multiplying 14 to x.

This leaves you with about      x<17.143
                                    or         x< 240/17 (as a fraction)
