Use the Distributive Property, then solve for #x#.

Explanation:

The Distributive Property states that #a(b+c)=a*b+a*c#. Let's use this to solve for the parentheses in our equation:

#3(x-4)=3*x+3*-4=3x-12#

We now have #3x-12=27#.

Next, let's add 12 to each side to get #3x=39#.

Finally, divide each side by 3 to get #x=13#.
