Explanation:

EDGE 2023 . I took the test and it shoed the right answer

Answer 2

The answer is a 3x2 matrix

Explanation:

From the given system of equation

The parameters of the variables x, y and z are outlined as the first column

And the integers on the other side are outline as the second column

This makes the matrix a 3rolls and 2 column matrix
