Let's start by combining the values that are similar... we have two values with a w so we can change the equation from
-6w-4+2w=4
to
-4w-4=4
Now, we want to get w alone and in order to do this, we must first make the -4 go away.
The basic rule of doing these problems is to know that anything you do to one side (such as subtract or add a number or divide or multiply by a number) must be done to the other side as well.
In order to get rid of the -4, we want to add 4, which we will do to both sides
-4w=8
now, in order to get w alone, we must divide by -4 on both sides
w=-2
