jim_thompson5910 · Answer

ok thx, a screenshot would be best

anonymous · Answer

here it is:

jim_thompson5910 · Answer

hmm very odd, none of the answer choices have an x in them

anonymous · Answer

i know thats why i dont get it.  should i just guess on it?

jim_thompson5910 · Answer

there's definitely a typo, so that's the best you can do really

I would mention it to your teacher

anonymous · Answer

i showed her it and she said the answer is there.

jim_thompson5910 · Answer

well that's simply not possible, there needs to be an x somewhere in the expression for it to be possible

anonymous · Answer

ill show her again. lol

jim_thompson5910 · Answer

if you had something like 3x - 3x, they would add to 0x or just 0

but that sort of thing doesn't happen here

anonymous · Answer

i just wrote to my teacher again. Thank you for all your help :D
