\"3x+%2B+5y+=+-48\"
\n" ); document.write( "\"4x+-+10y+=+-24\"\r
\n" ); document.write( "\n" ); document.write( "Divide both sides of the lower equation by 2, so the factor of y becomes opposite to the factor of y in the upper equation.
\n" ); document.write( "\"%284x+-+10y%29%2F2+=+%28-24%29%2F2\"
\n" ); document.write( "\"2x+-+5y+=+-12\"
\n" ); document.write( "Since they are now the opposite of each other they disappear when you add them.\r
\n" ); document.write( "\n" ); document.write( "Examples:
\n" ); document.write( "\"+-2y+%2B+2y+=+0\"
\n" ); document.write( "\"+123y+-+123y+=+0\"\r
\n" ); document.write( "\n" ); document.write( "So when you add the equations together you get this:\r
\n" ); document.write( "\n" ); document.write( "\"3x+%2B+2x+%2B+5y+-+5y+=+-48+-+12\"\r
\n" ); document.write( "\n" ); document.write( "\"5x+=+-60\"
\n" ); document.write( "\"x+=+-30\"
\n" ); document.write( "
\n" );
