A student puts a 3x3 system of linear equations is into an augmented matrix. The student then correctly
puts the augmented matrix into row echelon form (REF), which yields the following resultant matrix:
-2
3
-0.5
10
0 0
0
-2
0 1 -4
Which of the following conclusions is mathematically supported by the work shown about system of linear
equations?
The 3x3 system of linear equations has no solution.
○ The 3x3 system of linear equations has infinite solutions.
The 3x3 system of linear equations has one unique solution.
Solve the following system of equations using matrices: -2x + 4y = 8 and 4x - 3y = 9
Note: This is the same system of equations referenced in Question 14.
If a single solution exists, express your solution as an (x,y) coordinate point with no spaces. If there are infinite
solutions write inf and if there are no solutions write ns in the box.
