If you are trying to find w, then we would assume that all of this is equal to 0, and we would have to rewrite this equation.
-3(2w+6)-4=0
Now we are going to use the distribution property, to distribute the -4 to everything inside of the parenthesis. And that will get rid of the 4.
-3((2w*4)+(6*4))=0
next we are going to find what 2w*4 and 6*4 equal.
-3(8w+24)=0
Now this is an easier equation to work with. Divide both sides by -3, because whatever we do to one side we must do to the other.That will cross out the -3 on the left of the equation. And 0/-3 is equal to 0.
(8w+24)=0 or 8w+24=0
Now this is a 2 step equation, my favourite kind. we are going to subtract 24 from both sides. That will cancel out the +24 on the left.
8w=-24
And finally we divide both sides by 8. leaving us with
w=-24/8 or -3
<h2>So we now know that -3(2w+6)-4 is equal to <u><em>
w=-3</em></u></h2>
