Answer 2

Step-by-step explanation:

To solve for X, you first add the integers together and the X variables together. Then you subtract three from each side, followed by dividing by 3 on each side. Here is the work to show our math:

X + X + 1 + X + 2 = 120

3X + 3 = 120

3X = 120 -3

3X = 117

X = 39

Which means that the first number is 39, the second number is 39 + 1 and the third number is 39 + 2. Therefore, three consecutive integers that add up to 120 are 39, 40, and 41.

39 + 40 + 41 = 120

We know our answer is correct because 39 + 40 + 41 equals 120 as displayed above.
