Question

one number is 7 time another number if 18 is added to the sum of the number the result is 38 find the number ​

Answer 1

Answer:

Let the numbers be x and y such that

x=7y

We know ,

x+y+18=38      ---------------- (1)

x + y= 38-18

x+y= 20

7y + y = 20

8y = 20

y= 20/8

y = 2.5

put the value of y in equation 1, we get-

x + 2.5 + 18 = 38

x+ 20.5 = 38

x = 38-20.5

x = 17.5

Answer 2

Answer:

1st no. = 21

2nd no. = 3

Step-by-step explanation:

Let the number be x

A.T.Q

x⁷+ x + 14 = 38

x⁸ + 14 = 38

x⁸ = 38 - 14

x⁸ = 24

24/8x

= x + 3 + 14 = 39

3⁷ + 3 + 14 = 38

21 + 3 + 14 = 38

Ans = 1st no. = 21

2nd no. = 3
