Question

Choose the correct answer from the given four options :

If `[(x - 2y, 5),(3, y)] = [(6, 5),(3, -2)]` then the value of x is

पर्याय

• – 2

• 0

• 1

• 2

Answer 1

`[(x - 2y, 5),(3, y)] = [(6, 5),(3, -2)]` 
Comparing, we get
y = -2
and
x – 2y = 6
⇒ x – 2 x (-2) = 6
⇒ x + 4 = 6
⇒ x = 6 – 4 = 2.
