Solve the system using either Gaussian elimination with back-substitution or Gauss-Jordan elimination. (If there is no solution, enter NO SOLUTION. If the system has an infinite number of solutions, express x, y, z, and w in terms of the parameters t and s.)

4x	+	12y	−	7z	−	20w	=	20
3x	+	9y	−	5z	−	28w	=	36

(x, y, z, w) = ( )
