What is a valid proportion to represent the problem?

Sample response: To solve using equivalent ratios you would consider the values in both numberators. The second numerators. The second numerator is 2 times the value of the first, so the second denominator should be 2 times the value of the first. Thus, x should equal 6 because 2 times 3 is 6. Which facts did you include in your response?
