प्रश्न
Choose the correct answer from the given four options :
If `[(x + 2y, -y),(3x, 7)] = [(-4, 3),(6, 4)]` then the values of x and y are
विकल्प
x = 2, y = 3
x = 2, y = – 3
x = – 2, y = 3
x = 3, y = 2
उत्तर
`[(x + 2y, -y),(3x, 7)] = [(-4, 3),(6, 4)]`
Comparing, we get
3x = 6
⇒ = 2
⇒ -y = 3
⇒ y = – 3
x = 2, y = -3.
