You can put this solution on YOUR website!
Simply add the equations together to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "\r\n" );
document.write( "   8x - 7y = 49\r\n" );
document.write( "+ -8x + 7y = -49\r\n" );
document.write( "-----------------\r\n" );
document.write( "   0x + 0y = 0 \r\n" );
document.write( "         0 = 0\r\n" );
document.write( "\r\n" );
document.write( "

\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Since the equation is ALWAYS true, this means that the system is consistent and dependent. In other words, there are an infinite number of solutions. \n" ); document.write( "

\n" );
