Answer:

The numbers are: 1 and 3.

Step-by-step explanation:

Let the first number be [tex]$ x $[/tex] and the second number be [tex]$ y $[/tex].

Given: The difference between twice the number and the second number is [tex]$ -1 $[/tex]. writing this mathematically,

[tex]$ 2x - y = -1 $[/tex]

From the second statement we get:

[tex]$ 2y + 3x = 9 $[/tex]

Solving for [tex]$ x$[/tex] and [tex]$ y$[/tex] we get:

[tex]$ x = 1 $[/tex]

and [tex]$ y = 3 $[/tex]

Thus the first number is 1 and the second number is 3.
