Question

Solve the system of equations using matrices. Use Gaussian elimination with back-substitution or Gauss-Jordan elimination. Express the solution set as \{(w,x,y,z)\}. 3w+4x+3y- 3z = 38 w+x-y+z= 2 3w+x-2y-2z = 11 -w+2x+y-3z = 6 The solution set is \{\boxed{\hspace{0.5cm}},\boxed{\hspace{0.5cm}},\boxed{\hspace{0.5cm}},\boxed{\hspace{0.5cm}}\}. (Simplify your answers.)
