You can put this solution on YOUR website!
$\"+8x+-+4y+=+16+\"$
\n" ); document.write( " $\"+y+=+2x+-+4+\"$
\n" ); document.write( "Plug the second equation into the first
\n" ); document.write( " $\"+8x+-+4%282x+-+4%29+=+16+\"$
\n" ); document.write( "Distribute
\n" ); document.write( " $\"+8x+-+8x+%2B+16+=+16+\"$
\n" ); document.write( "combine x values
\n" ); document.write( " $\"+16+=+16+\"$
\n" ); document.write( "Since they are the SAME solution, it means they are the same line. \n" ); document.write( "
