X=3+12

X=15

Answer 2

The two numbers are 15 and 12.

Step-by-step explanation:

Let the two numbers be x and y.

The information provided is:

x + y = 27...(i)

x -  y = 3...(ii)

Add equations (i) and (ii) and solve for x as follows:

x + y = 27

x -  y = 3

_______

2x = 30

x = 15

Substitute the value of x in (i) and solve for y as follows:

x + y = 27

15 + y = 27

y = 27 - 15

y = 12

Thus, the two numbers are 15 and 12.
