Question

if systam of equation has unique solution than number of solution is
a 2
b. 3
C. 5
d. 1​

Answer 1

A nxn homogeneous system of linear equations has a unique solution (the trivial solution) if and only if its determinant is non-zero. If this determinant is zero, then the system has an infinite number of solutions.

Answer 2

Answer:

, there is always at least one solution, the point (0,0). ... A nxn homogeneous system of linear equations has a unique solution (the trivial solution) if and only if its determinant is non-zero. If this determinant is zero, then the system has an infinite number of solutions.
