Question

the sum of two numbers is 9. if one number is twice the another number find the two numbers


pls say the correct answer​

Answer 1

Step-by-step explanation:

let the unknown number be x

if one number is twice the other then 2x

x+2x=9(equation)

3x=9

x=9/3

x=3

the unknown numbers are

x=3

2x=6

Verification

x+2x=9

3+6=9

hence , verified

Answer 2

Step-by-step explanation:

Let two numbers are x and y.

Given: The sum of two numbers is 9, Therefore,

x + y = 9

And, one number is twice the other number, so,

x = 2y

Substitute value of x = 2y from equation (2) in equation (1), we get,

2y + y = 9

3y = 9

y = 3

Now, putting value of y = 3, in equation (2), we get,

x = 2 × 3 = 6

Hence, the numbers are 6 and 3.
