Sam is 36. he is 3 times as old as tracey’s and dan’s ages combined. tracey is 5. if d represents dan’s age, which equation could be used to find dan’s age?

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
