Let's solve this inequality!


\rm{-x+20>-7+35

What can we do to solve this inequality? Well, first of all, we can add -7 and 35:


\rm{-x+20>28

Now, move 20 to the right, using the opposite operation:


\rm{-x>28-20

Subtract:


\rm{-x>8

Divide both sides by -1 to isolate x:


\rm{x<-8} (Answer)

_____________

Additional comment

When we divide both sides of an inequality by a negative number, we flip the inequality sign.
