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 = 243
3X + 3 = 243
3X + 3 - 3 = 243 - 3
3X = 240
3X/3 = 240/3
X = 80
Which means that the first number is 80, the second number is 80 + 1 and the third number is 80 + 2. Therefore, three consecutive integers that add up to 243 are 80, 81, and 82.
80 + 81 + 82 = 243
We know our answer is correct because 80 + 81 + 82 equals 243 as displayed above.
