Question

3(x – 4) = 33
Prove: x = 15
3x – 12 = 33 would be an example of what?

Answer 1

Are we solving both of those questions?

Answer 2

Is this about properties as well?

Answer 3

I would have divided both sides by 3 to get

x - 4 = 11

Answer 4

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

Answer 5

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

Thankyou :D
