The answer is 63. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
54 ÷ 6 + 36 + 9 = 54
9 + 9 + 9 + 9 + 9 + 9 = 54
18 + 36 + 45 + 9 + 9 + 54 + 27 + 72 + 81 = 351
9 + 6 / 54 = 9 + 1/9 = 82/9 or 9.11...
54
45 + 9 = 54
9 15+39=54 54/6=9
45 with the difference of 9 = 54
4x + 4 + 14 = 54 4x + 18 = 54 4x = 54 - 18 4x = 36 x = 36/4 x = 9 Check: 4(9) + 4 + 14 = 54 36 + 18 = 54 54 = 54
54
1/9 + 5/6 = 6/54 + 45/54 = 51/54 = 17/18 <-------------------------
X + 6*9 = X + 54
