=(3 times 2)x - (3 times 4)y
=6x-12y

You just need to carry the process through...
3(2x-4y) = (3 times 2x) - (3 times 4y)
which works out to : 6x - 12y

You need to distribute. You can do this by multiplying each part of the problem by 3.
3(2x - 4y) = 6x - 8y

You multiply what is outside the bracket by each term that is inside it.
6x-12y

1. its called the distributive property. multiply whats outside the parentheses by whats inside them.
2. a "please" would have been nice.
