To find the answer, you must simply work backwards. So add 9 to 51, and divide your answer by 3. The answer is 20

As with all questions like this, you must work backwards. If (n x 3) - 9 = 51, you must start at the end, in this case -9. 51 - 9 = 46. Therefore n x 3 = 46. Then you must divide 46 by 3 to find n. 46 ÷ 3 = n. 46 ÷ 3 = 15.3 recurring. Therefore n = 15.3 recurring
