Answer 2

Answer:

7 and 4

Step-by-step explanation:

Let the numbers be x and y.

According to the problem,

                                         2x - 3y = 2

  and                                 x + y = 11

Multiplying both sides of (ii) by 3, we get

                            3x + 3y = 33

On adding (i) and (iii), we get

                                            5x = 35  =>    x = 7

Substituting this value of x in (ii), we get

                           7 + y = 11  =>  y = 11 - 7  =>   y = 4

Hence, the required numbers are 7 and 4.
