Find the values of x and y respectively if [[2x + y, 4], [5, x − y]] = [[10, 4], [5, 2]].
Find the values of x and y respectively if [[2x + y, 4], [5, x − y]] = [[10, 4], [5, 2]].
- A. 4, 2
- B. 2, 4
- C. 3, 4
- D. 4, 3
Answer: A) 4, 2
Explanation: Equating corresponding elements: 2x + y = 10 and x − y = 2. Adding them gives 3x = 12 → x = 4. Substituting x = 4 gives 4 − y = 2 → y = 2.
