Question

If x+y = 8, x2 – y 2 = 16, then x – y = ______​

Answer 1

Answer:

The value of ( x - y ) is 2

Step-by-step explanation:

Given that,

x + y = 8

x² - y² = 16

Required to find,

x - y

Procedure,

We know,

    x² - y² = ( x + y )( x - y )

=> 16 = 8( x - y )

=> 8( x - y ) = 16

=> ( x - y ) = 16/8

=> ( x - y ) = 2

So ( x - y ) = 2

Ans:- The value of ( x - y ) is 2
