(adsbygoogle = window.adsbygoogle || []).push({}); Help!! System of equations!

For a natural number define the n*n matrix A = (aij) by setting aij = min(i,j). Write down the matrix a for a few values of n = 2,3,4...... Show that A is invertible and find its inverse.

Hence or otherwise show that the system of equations Ax =b , where x=(x1,....xn) and b=(b1.....bn) has a unique solution.

Anyone help with how to solve that?

Thanks

Rob and Joanna!
