John and Anna entered a giant pumpkin contest. John's three pumpkins weighed 2n + 1.2 pounds each. Anna's six pumpkins weighed 30-4 pounds each. The total weight of John's 3 pumpkins was the same as the total weight of Anna's six pumpkins. This situation can be expressed with the equation below. (2n + 1.2) + (2n+ 1.2) + (2n + 1.2) = (3n-4) + (30-4) + (3n-4) + (3n-4) + (30-4) + (30-4) What value of n makes this equation true?
