Question

The sum of 3 consecutive integer is 45 . What are these integers

Answer 1

Answer:

14+15+16=45

Step-by-step explanation:

LET THE INTEGERS BE X,X+1,X+2

X+X+1+X+2=45

3X=45-3

X=14

X+1=15

X+2=16

Answer 2

Answer:

1st number = x

2nd number = x+1

3rd number = x+2

x + ( x + 1 ) + ( x + 2 ) = 45

Step-by-step explanation:

3x + 3 = 45 (after adding up)

3x = 45 - 3 (remember after transposing the operation changes to opposite , for eg : - to + , + to - , and so on)

3x = 42 , x = 42 (3×14=42)

3

x = 14

First number = 14

Second number = 14 + 1 = 15

Third number = 14 + 2 = 16
