उत्तर
If `[(x + 2, 7),(y + 3, a - 2)] = [(4, b - 3),(4, 3)]`, the value of x, y, a and b are x = 2, y = 1, a = 5 and b = 10.
Explanation:
Given
`[(x + 2, 7),(y + 3, a - 2)] = [(4, b - 3),(4, 3)]`
Thus their corresponding elements are equal.
∴ x + 2 = 4 `\implies` x = 4 – 2 = 2
y + 3 = 4 `\implies` y = 4 – 3 = 1
7 = b – 3 `\implies` b = 7 + 3 = 10
a – 2 = 3 `\implies` a = 3 + 2 = 5
