Answer:

  • The required values are 6 and 3.

Step-by-step explanation:

Let the numbers be x and y. Now, We have to follow the question's statement. First of all, we have to form equations according to the question's statement.

  • x + y = 9
  • x - y = 3

Solve the question by elimination method.

  • x + y = 9
  • x - y = 3

_______________

  • 2y = 6
  • y = 6/2
  • y = 3

Put the value of y in equation 1.

  • x + y = 9
  • x + 3 = 9
  • x = 9 - 3
  • x = 6

Therefore, the required values are 6 and 3.
