\n" );
document.write( "Hi,
\n" );
document.write( "9x + 4y = 104 
\n" );
document.write( " x - 5y = 17        |Multiplying 2nd EQ by 9 and subtracting from the 1st EQ to eliminate x
\n" );
document.write( "    49y = -49
\n" );
document.write( "        y = -1  and x = 12      \n" );
document.write( "

\n" );
