Step-by-step explanation:

In the matrix, the first column represents the coefficient of x, the second column represents the coefficient of y and the third column is the constant value.

As the first row is (1 0 | 3), the equation is

1x + 0y = 3

x = 3

The second row is (0 1 | -6), so the second equation is

0x + 1y = -6

y = -6

It means that the system of equations is

x = 3

y = -6

Therefore, the system is consistent because it has a solution, the solution is (x, y) = (3, -6)

Answers:

What equation does the first row represent? x = 3

What equation does the second row represent? y = -6

A. The system is consistent. The solution is (3, -6)
