Question

3
: A Complete the given activity.
Solve : 97x + 103 y = 497 ; 103x + 97y = 503
ation :
103x + 97y = 503 ... (1)
97x + 103y = 497 (II)
200x + 200y
Adding (1) and (II)
Dividing by 200, we get
:: x + y =
....(III)
+
103x + 97y - 503 .. (1)
-97x = 103y = -497
- бу = 6
by subtracting (II) from (1)
Dividing the equation by 6, we get
:: x - y = .... (IV)
By solving equations (III) and (IV) we get,
; y =​
