Answer: There were 78 red apples at the party.

Step-by-step explanation:

This situation can be represented by the equation

x + 3x + 2 (3x) = 130 where x is the number of green apples, 3x is the number of yellow apples and 2 (3x) is the number of red apples.

Now solve for x

x + 3x + 2 (3x) = 130

4x + 6x = 130

10x = 130

x = 13

Now we know that x is 13 so put it into the expression for red apples and solve for the actual number of red apples.

2 * (3*13) = ?

2 * 39 = 78
