Solve the following system of linear equations using Gaussian elimination or Gauss-Jordan elimination. Z HE -2x+y = -7 -2y-z = 0 -x+3z = 3 NOTES: If there is/are: -> one solution, give its coordinates (point) in the spaces above. This is how most solutions will be entered on this assignment. -> infinitely maky solutions, enter z in the space for z, an expression in terms of z (that represents y) in the space for y, and an expression in terms of z (that represents ) in the space for z. -> no solutions, enter None in each of the spaces. Note: In order to get credit for this problem all answers must be correct.
