5x-2y+z=3
\n" ); document.write( "౩x+2y+7z=5
\n" ); document.write( " X+y+3z=2
\n" ); document.write( "=============
\n" ); document.write( "Add eqns 1 & 2
\n" ); document.write( " 5x-2y+z=3
\n" ); document.write( "౩x+2y+7z=5
\n" ); document.write( "----------------
\n" ); document.write( "8x + 8z = 8 Eqn A
\n" ); document.write( "------------------
\n" ); document.write( "Add eqn 1 and 2x eqn 3
\n" ); document.write( " 5x-2y+z=3
\n" ); document.write( " 2x+2y+6z=4
\n" ); document.write( "---------------- Add
\n" ); document.write( "7x + 7z = 7 Eqn B
\n" ); document.write( "Eqns A & B are equivalent.
\n" ); document.write( "--> No unique solution. \n" ); document.write( "
