Solve the system of linear equations, using the Gauss-Jordan elimination method. (If there is no solution, enter NO SOLUTION. If there are infinitely many solutions, express your answer in terms of the parameterstand/ors.)

A)

3y+2z=12

xy3z=42

x+2yz=5

(x,y,z) =

B)

x+y2z=22

xy+3z=6

x2y+5z=1

(x,y,z) =

C)

x₁2x₂+x₃=22

x₁+x₂2x₃=3

x₁+3x₂3x₃=5

(x₁,x₂,x₃) =
