प्रश्न
If `[(1, 2),(3, 3)] [(x, 0),(0, y)] = [(x, 0),(9, 0)]`find the values of x and y
उत्तर
Given
`[(1, 2),(3, 3)] [(x, 0),(0, y)] = [(x, 0),(9, 0)]`
⇒ `[(x + 0, 0 + 2y),(3x + 0, 0 + 3y)] = [(x, 0),(9, 0)]`
⇒ `[(x, 2y),(3x, 3y)] = [(x, 0),(9, 0)]`
Comparing the corresponding elements
2y = 0
⇒ y = 0
3x = 9
⇒ x = 3
Hence x = 3, y = 0.
