Answer:

Concept: Mathematical Representation

  1. You have a two digit # __
  2. The sum of the two digit # = 13
  3. The original # increased by 9
  4. Hence we must find values that sum to 13. *Note they must be independently standing.
  5. 8+5, 9+6, 7+6 , 6+7 , and etc
  6. The value must also increase by 9
  7. So logically it would be any result that when switched that value would be 76-67= 9.
  8. So the value must be 67

r+.2 = -3

Subtract .2 from each side

r+.2-.2 = -3-.2

r = -3.2
