Final answer:
The solutions to the equation ax = 0 can be found by setting 'a' equal to the zero vector.
Step-by-step explanation:
The equation ax = 0 represents a system of linear equations in vector form. In this equation, 'a' is a vector and 'x' is an unknown vector. The solutions to this equation can be found by setting 'a' equal to the zero vector. In other words, if 'a' is the zero vector, then any vector 'x' will satisfy the equation ax = 0.
