<PRE><B>Question 37234</B>
Whatever you do on the Left Hand Side, do the same on the Right Hand Side

All you have to do is add the Like terms and simplify keeping the above tip in mind

[5-4w+12=-5w-16]

Adding like terms
5+12 =7
Adding +4w on both sides
17 = -5w-16 +4w
17 = -w-16
Adding +16 on both sides
33 = -w
Multiplying both sides with a Negative Sign
w = -33</PRE>
