Answer:

  10, 13

Step-by-step explanation:

Let x represent the smaller number. Then the larger one is (1 +30%)x = 1.3x. Their sum is ...

  x + 1.3x = 23

  2.3x = 23 . . . . . . . . collect terms

  x = 23/2.3 = 10 . . . divide by the coefficient of x

  1.3x = 13 . . . . . . . . . find the larger number

The two numbers are 10 and 13.
