Question

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, set w = t and y = s and solve for x and z in terms of t and s.) 4x + 12y - 7z - 20w = 20 3x + 9y - 5z - 28w = 36 (x, y, z, w) =
