Shelby is organizing the 12 prize ribbons she won for athletic competitions. she has twice as many first place ribbons as she does second place ribbons. how many first place ribbons does she have?

I think she has for because 2x+x=12
3x=12
X=4

I would use the box method to solve this problem. Since she has twice as many, you add the 2 to the 1 to get three. Then you divide the total amount (12) by 3. So, 4 goes in each of the 3 boxes. This tells you that there are 8 first place ribbons and 4 second place ribbons. Hope this helps.
