di sankhyao ka anter 4 h ir unke vilomo ka anter4/21 h to sankhya pta karo​

Answer 1

⭐ Answer⭐

➡let, Two number are x and y.

➡let, Two number are x and y. [ So according to question . ]

✴ x-y = 4...........(1)

✴1/x - 1/y = 4/21.......(2)

=> (x-y)= 4xy /21.

[ keep value by (1) ]

=> (4) = 4xy/21

=> xy = 21...................(3)

[ we , know ]

✴(a+b)²= (a-b)²+4ab.

by (1) and (3) .

=> (x+y)²= (4)²+4×21

=>(x+y)²= 16+84

=> (x+y)²= 100

=>x+y = 10............(4)

Now, solve equation (1) and (4)

Adding both equations .

=> 2x = 14

$\implies\red{\bold{\:x\:=\:7}}$

keep value in (5) ,

=> 7 +y = 10

=> y = 10-7

$\implies\red{\bold{\:y\:=\:3}}$
