Question 215608
the difference between a number and 9 is the same as 35 less than the number
-------------------
Equation:
Let the number be "x":
9-x = x-35
2x = 9+35
2x = 44
x = 22
------------------
Note: You have to use 9-x for the difference.
If you use x-9 as the difference you get
x-9 = x-35 which is a contradiction.
=========================
Comment: That is not really a good problem because
of the ambiguity in sybolizing "the difference 
between a number and 9".
