Number of Shares: x+y+z=250\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Cost of Shares: 16x+5y+80z=11200\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Dividends: 0.07x+0.02y+0.02z=304\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Use Gaussian elimination to solve for x,y, and z.
