Are we solving both of those questions?

hero · Answer

Is this about properties as well?

hero · Answer

I would have divided both sides by 3 to get

x - 4 = 11

anonymous · Answer

it's the same thing I just added a bit more to it

johnweldon1993 · Answer

Well

Prove x = 15

Just plug it in for x in the equation

3(x - 4) = 33
3(15 - 4) = 33
3(11) = 33
33 = 33

so that is proven...

Now....what is THAT an example of?

going from 

3(x - 4)

to

3x - 12

Is called the distributive property...when you apply the number on the outside of the parenthesis to each term in the parenthesis
