Multiply by (-5) instead of (5):
\n" ); document.write( "-5(3x-9y=10
\n" ); document.write( "15x-45y=20
\n" ); document.write( "________________
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "-15x+45y=-50
\n" ); document.write( "+15x-45y=20
\n" ); document.write( "________________
\n" ); document.write( "0 = -30 (false statement)
\n" ); document.write( ".
