Question

−4x−8>−20 Whats the answer please help

Answer 1

Think:  "isolate x."  Also, remember that when you mult. or div. terms in an inequality by a neg. # you must reverse the direction of the inequality symbol.

−4x−8>−20 becomes  4x + 8<20 after dividing the original by -1 and then reversing the direction of the inequality symbol.

Now isolate x, first by subtract 8 from both sides and then dividing the result by 4:

       4x + 8 < 20
            - 8 <  -8
----------------------
         4x < 12

Divide both sides by 4:  x < 3  (answer)
