Answer 1

Answer:

14 + 15 + 16 = 45 . Let the three consecutive integers be x, x+1 and x+2. Therefore the numbers would be 14, 15 & 16. answer: 14, 15 and 16.

Step-by-step explanation:

Answer 2

Call n the first integer so you get:

$n + ( n + 1 ) + ( n + 2 ) = 45$

$3 n + 3 = 45$

$3 n = 42$

$n = 14$

The integers are: 14 , 15 , 16
