Question

Which of the following is the solution to the inequality below?

-5x - 10 < 20 ?

1) x > -6
2) x > - 2
3) x < -6
4) x< -2

Answer 1

Add 10 to both sides.

This gives us -5x < 30.

Now divide both sides by -5.

When you divide both sides of
an inequality by a negative, switch
the direction of the inequality symbol.

So we have x > -6.
