$w = 0$

Using the distributive law, the 3 outside the bracket is multiplied by each term inside the bracket.
$3(w-4)=-12$
$3w-12 = -12$

Now solve for w

$3w = 0$
$w = 0$
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Dividing by 3 first will give the same result.

$(3(w-4))/3=-12/3$

$w-4 = -4$

$w = 0$

How do you multiply 3 (w-4) = -123 (w-4) = -12?
