Question

the sum of 3 consecutive integers is 45 what are this integer

Answer 1

Bonjour!!

Let the three consecutive numbers be x, x + 1, x + 2

x + x + 1 + x + 2 = 45
3x + 3 = 45
3x = 42
x = 42/3
x = 14

First integer = 14
Second integer = 15
Third interger = 16

Answer 2

x,x+1,x+2=45
3x+3=45
3x=45-3
3x=42
x=42/3
x=14
x+1=14+1
:15
x+2=14+2
:16
