(x + y, 0) = (1, x - y) হলে, (x, y) এর মান কত?

A  (1, 0) 

B (1/2, 1/2)  

C (1/2, 2)  

D (1/4, 1/4)  

Solution

Correct Answer: Option B

দেওয়া আছে,
x + y = 1 ................. (1)
x - y = 0 .................. (2)

(1) - (2) হতে পাই,
2y = 1
∴ y = 1/2

y এর মান (1) নং এ বসিয়ে পাই,
x + 1/2 = 1
⇒ x = 1 - 1/2
∴ x = 1/2

(x, y) = (1/2, 1/2)
