Question

The sum of two numbers is 9 and their difference is 1 what are the two numbers

Answer 1

5 and 4 are the numbers.

Answer 2

Answer:

5 and 4

Step-by-step explanation:

Let the two numbers be x and y respectively.

According to the question ;

x + y = 9   ....(i)

x - y = 1     .... (ii)

Adding equation (i) and (ii),

⇒ x + y + x - y = 9 + 1

⇒ 2x = 10

⇒ x = $\dfrac{10}{2}$

⇒ x = 5

Now, substituting the value of x in equation (i), we get ;

x + y = 9

⇒ 5 + y = 9

⇒ y = 9 - 5

⇒ y = 4

Hence, the required numbers are 5 and 4 respectively.
