Answer:
3X + 3 = 168
3X + 3 - 3 = 168 - 3
3X = 165
3X/3 = 165/3
X = 55
Step-by-step explanation:
We start by assigning X to the first integer. Since they are consecutive, it means that the 2nd number will be X + 1 and the 3rd number will be X + 2 and they should all add up to 168. Therefore, you can write the equation as follows: (X) + (X + 1) + (X + 2) = 168
