(Select all that apply) Leading variables: 082 no leading variables not in echelon form Free variables: no free variables O not in echeion form Ir not, explain why not. ãThe linear system is not in echelon form since x,is a leading variable in both equations. O The linear system is not in echelon form since there are no free variables O The linear system is not in echelon form since there are no leading variables O The linear system is not in echelon form since x2 is a leading variable in both equations O The linear system is in echelon form
