​

Answer 1

$\huge\mathcal\red{Answer}$

⭐Let the 2 numbers be x and y .

↪ Given : x+y= 39 and x-y=15

✅Now....Add these 2 equations....

Therefore....we get ,

⭐2x= 54

⭐x=27

↪ y= 39 - x = 39 - 27 = 12...

⏩ X = 27

⏩Y = 12

Answer 2

Answer:

27 and 12

Step-by-step explanation:

Let the two numbers be x and y respectively.

According to the question ;

x + y = 39    ....(i)

x - y = 15      .... (ii)

Adding equation (i) and (ii),

⇒ x + y + x - y = 39 + 15

⇒ 2x = 54

⇒ x = $\dfrac{54}{2}$

⇒ x = 27

Now, substituting the value of x in equation (i), we get ;

x + y = 39

⇒ 27 + y = 39

⇒ y = 39 - 27

⇒ y = 12

Hence, the required numbers are 27 and 12 respectively.
