Question
The equation 2x + 5y = 7 has a unique solution, if x, y are:
✓

Answer

  1. Natural numbers.
    Solution:
    There is only one pair i.e., (1, 1) which satisfies the given equation but in positive real numbers, real numbers and rational numbers there are many pairs to satisfy the given linear equation. Hence, unique solution is possible only in case of Natural numbers.
