Consider the following system system of equations x1-2x3=0 x1-x2=0 2x1-2x2=0
rank of matrix is less than n(3<2).....take any variable as orbitory value....(infinite no of solution)
Consider the following system system of equations
x1-2x3=0 -> x1=2x3 x1-x2=0 -> x1 = x2 2x1-2x2=0 -> x1 = - x2
Here every variable take more than 2 value Thus system have infinite solution.
