Question

The sum of three consecutive integers is 39. Write an equation to model the situation

Answer 1

Answer:

let the numbers be x, x + 1 , x + 2

then

x+x+1+x+2 = 39

3x + 3 = 39

x+1= 13

x = 12

Answer 2

ANSWER

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

Let x,x+1,x+2 be the three consecutive numbers.Sum=x+x+1+x+2=39

Let x,x+1,x+2 be the three consecutive numbers.Sum=x+x+1+x+2=39⇒3x+3=39

Let x,x+1,x+2 be the three consecutive numbers.Sum=x+x+1+x+2=39⇒3x+3=39⇒3x=39−3=36

Let x,x+1,x+2 be the three consecutive numbers.Sum=x+x+1+x+2=39⇒3x+3=39⇒3x=39−3=36⇒x=

Let x,x+1,x+2 be the three consecutive numbers.Sum=x+x+1+x+2=39⇒3x+3=39⇒3x=39−3=36⇒x= 3

Let x,x+1,x+2 be the three consecutive numbers.Sum=x+x+1+x+2=39⇒3x+3=39⇒3x=39−3=36⇒x= 336

=12 on simplifying.

The numbers are 12 , 12+1, 12+2

Hence the three consecutive numbers are 12,13,14
