Answer 2

The numbers are "6 and 2".

Step-by-step explanation:

Let two numbers = x and y

To find, the numbers = ?

According to question,

$x+y=8$      ....(1)

Also,

$x-y=4$     ....(2)

Adding (1) and (2), we get

$x+y+x-y=8+4$

⇒ $2x=12$$x+y+x-y=8+4$  

⇒ $x=\dfrac{12}{2} =6$

Put x = 6 in (1), we get

$6+y=8$

⇒ $y=8-6=2$

Hence, the numbers are "6 and 2".
