1. 2x+3y=36 এবং 2x+y=16 হলে (x, y) এর মান কত?

  • A. (2, 10)
  • B. (2, 10)
  • C. (2, 10)
  • D. (2, 10)

Answer: Option B

Explanation:

এখানে, 2x + 3y = 36

বা, 2x = 36 - 3y

আবার, 2x + y = 16

বা, 36 - 3y + y = 16

বা, - 2y = 16 - 36 = - 20

বা, y = 10

তাহলে, 2x = 36 - 3y = 36 - 3 x 10 = 36 - 30 = 6

বা, x = 3.

সুতরাং, (x, y) = (3, 10)
