যদি 4(x - y) = 64 এবং 4(x + y) = 1024 হলে, x এর মান কত?
Solution
Correct Answer: Option B
4(x - y) = 64
বা, 4(x - y) = 43
বা, x - y = 3 ........................(1)
আবার,
4(x + y) = 45
বা, x + y = 5 .......................(2)
(1) + (2) হতে পাই,
2x = 8
∴ x = 4
বা, 4(x - y) = 43
বা, x - y = 3 ........................(1)
আবার,
4(x + y) = 45
বা, x + y = 5 .......................(2)
(1) + (2) হতে পাই,
2x = 8
∴ x = 4
