\r\n" );
document.write( "First take off the sign \"$\".\r\n" );
document.write( "\r\n" );
document.write( "4x + 9y = 190    (1)\r\n" );
document.write( "5x + 6y = 185    (2)\r\n" );
document.write( "\r\n" );
document.write( "Multiply equation (1) by 5 (both sides) and the equation (2) by (-4), then add. In this way you eliminate x and will get a single equation for y:\r\n" );
document.write( "\r\n" );
document.write( "45y + (-4)*6y = 5*190 - 4*185,   or\r\n" );
