Answer:
The numbers are 28, 29 and 30
Explanation:
We consider the first number as X, the second consecutive number is X+1 and the third is X + 2. The sum of these 3 numbers is 87, so:
X + X+1 +X+2 = 87
3x + 3 = 87
We substract 3 on both sides of the equation
3x + 3 - 3 = 87 - 3
3x = 84
We divide by 3 on both sides
x = 28
This means our numbers are 28, 29 and 30
