7) circle all of them8) write 1/the number it is seperatedby for all three and just divide the shapes evenly9) in thing order: no.no.yes,yes
The answer is X = 5 because first you have to take away 2x from that side so u minus 2x from 4x that gives u: 72 + 2x = 82 then you have to minus 72 from both sides and that gives you 2x = 10 once you have that you divide both sides by 2 because you want the X by itself and once you get that X = 5. Hope this helped!
