You can simplify 2(x-6) the way you described: 2x -12

But x(5+2) .. just add 5 and 2. :)  7x.

yes

anonymous · Answer

so the final answer is written like this?
2x-12+7x-7x+4?!

anonymous · Answer

cant i cancel out the 7x's?

lilg132 · Answer

so when you expand the brackets you should get

2x - 12 +7x - 7x + 4

and to simplify just put it in order

2x + 7x - 7x + 4 - 12

so you should get 2x - 8

That's not quite it, but you're close. 

Collect all the x terms:  +2x +7x -7x 
Collect the constant terms: -12 +4

yes thats what happens after expanding you cancel out the 7x
