adult tickets --- x

student tickets --- 8-x

solve for x

9x + 7(8-x) = 66

9 x 5 adults + 7 (8-5)= 66

45 + 7 (3)kids = 66

45 + 21 = 66

Now I found 5 adults by multiplying 9 x 5=45 just because that's the only way I know... Now I have no idea how to find x other than that. I am trying to help my 3rd grader with that. Please help.
