Question

The matrix below represents the solution to a system of equations.

1 0 0 | -3
0 1 0 | 2
0 0 1 | -1
Which of the following describes the solution?
A. No Solution
B. An infinite number of solutions
C. (-3, 2, -1)
D. (1, 1, 1)

Answer 1

The augmented matrix translates to

x = -3

y = 2

z = -1

so the third option (-3, 2, -1) is the correct choice.
