precalculus matrices

Question

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 parameters t and/or s.)

3y	+	2z	=	5
2x	−	y	−	3z	=	2
2x	+	2y	−	z	=	7

Answer 1

x=0

y=2.714

z=-1.571

Using a 3x4 matrix and RREF.

But you can't use Gauss Jordan because the Determinant is 0.

therefore, NO SOLUTION
