x=???

anonymous · Answer

:-) let's do it together kk .?

anonymous · Answer

Sighh okay. I am a total idiot when it comes to this.

anonymous · Answer

nobody is an idiot ! everybody is learning ! 
$$2x-7=x+1$$ 
$$2x-7-x=1$$ 
$$2x-x-7=1$$ so $$2x-x=x$$ ( like two books minus 1 book =1book)
then x-7=1

anonymous · Answer

now did you understand all parts ?!

anonymous · Answer

Yes I actually do! Okay so I've written this all down and I think I got it. x=8

anonymous · Answer

yeaaaah right ! !!!! you're smart ! ! don't  ever call yourself an idiot !!
