Question

99x + 101y = 35; 101x + 99y = 501​

Answer 1

Answer: x=3 y=2

Step-by-step explanation:

Answer 2

⇒Answer :

99 x + 100 y = 499

101 x + 99 y = 501

Adding Both Equations :

⇒200 x  + 200 y = 1000

⇒ x + y = 5 ---- (1)

Subtracting Both Equations :

⇒2 y - 2 x = -2

⇒ x-y = 1 ----- (2)

Adding (1) & (2)

⇒2 x = 6

⇒ x = 3

Thus,

3 + y =5

⇒ y =2
