Which mathematical sentence most accurately expresses the information inthe problem below?

SOLUTION
We are told that Christine has 9 shinning rings, and that if 5 of them are gold, how many are not gold?
Let the number of the rings that are not gold be n,
Since she has 9 rings and 5 are gold, then the numbers that are not gold which is n becomes
[tex]9\text{ shinning rings - 5 gold rings}[/tex]So,
[tex]n=9-5[/tex]If we bring -5 to meet n, then the minus sign becomes a plus sign, we have
[tex]n+5=9[/tex]Hence, the answer is option D
[tex]n+5=9[/tex]
