Question

If 13x +12y= 7 and 12x +13y=5 then x-y=??

Answer 1

Hey Mate !

Here is your solution :

=> 13x + 12Y = 7 ----------- ( 1 )

=> 12x + 13Y = 5 ---------- ( 2 )

By subtracting ( 2 ) from ( 1 ),

=> 13x + 12Y = 7

=> 12x + 13Y = 5

---------------------------

=> x - Y = 2

Hence, the required answer is 2.
