Question

The sum of three consecutive integers is 57. Find the integers.

Answer 1

Step-by-step explanation:

x+x+1+x+2=57

3x+3=57

3x=57-3

3x= 54

x= 54/3

x= 18

intergers are

x= 18

x+1= 18+1=19

x+2=18+2=20

Answer 2

Step-by-step explanation:

Consecutive" means that the integers will follow each other in value, for example: 1, 2, 3 or 4, 5, 6.

Also, no decimals are needed here because "integers" are whole, counting numbers.

Here is the set up:

Let x= the first integer

Then X+1= 2nd consecutive integer

and x+2= 3rd .

then X + X +1 + X + 2 = 57

3X + 3 = 57

3X = 57 - 3

3X = 54

X = 54/3

X = 18

so, three consecutive integers

X = 18

X + 1 = 19

X + 2 = 20
