Explanation:

Let x be the first number

Let y be the 2nd number

given,


x = 3y - 11 \\ x - 3y = - 11

as equation 1

and


x + y = 25

as equation 2.

Now we will use elimination method to solve for simultaneous equations.

We will use equation 1 - equation 2 to eliminate x to solve for y.


x - x - 3y - y = - 11 - 25 \\ - 4y = - 36 \\ y = - 36 / - 4 \\ = 9

Substitute y into equation 2.


x + 9 = 25 \\ x = 25 - 9 \\ = 16

The numbers are 9 and 16.
