Question

The sum of two consecutive even number is 42, then find the integer​

Answer 1

Step-by-step explanation:

let the integers be 2x and 2x+2 [ two consecutive integers differ by 2 and even integers are taken as 2x]

2x + 2x + 2 = 42

4x + 2 = 42

4x = 40

x = 10

therefore two consecutive integers are

2x = 20 and 2x + 2 = 22

Answer 2

Answer:

let the one no. be x

let the other no. be y

according to given situation:x+y=42..........(1)

now we know that these no. are even consecutive so y=x+2........(2)

(because if x is even then x+1 will be odd )

put value of y in (1)

x+x+1=42

2x+2=42

X=20

put x in (2)

y=20+2

Y=22
