उत्तर
Only (ii)
Explanation:
(i) The solution of the system of equations 3x + 4y = 25 and 4x + 5y = 32 is not x = 2, y = 1.
The correct solution for this system is x = 3 and y = 4.
Therefore, statement (i) is false.
(ii) For the equation ax + by = a + b, if x = 1 and y = 1, substituting gives a(1) + b(1) = a + b, which is true for all values of a and b.
Hence, statement (ii) is true.
Thus, only (ii) is valid.
