If you want to get the refined echelon form, do you just use the same transformations that you use for obtaining the row echelon form and do it as long as necessary to get to the refined echelon form?

sheet 2, 3.1, shouldn’t the answer be: cannot solved by cramers rule? and how du you conclude that the system has infinitely solutions? couldn’t it be also no solution?
