Mathematics

Nina [5.8K]3 years ago

Answer:

The numbers are 28, 29 and 30

Step-by-step 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
