PROBLEM 34E

Suppose A is a 4 × 3 matrix and b is a vector in ℝ4 with the property that Ax = b has a unique solution. What can you say about the reduced echelon form of A? Justify your answer.

ANSWER:

Solution

Step 1 of 2

Suppose A is a 4 × 3 matrix and b is a vector in ℝ4 with the property that Ax = b has a unique solution.

Since, Ax = b has a unique solution and it has no free column. So all the column of A are pivot column.
