You can put this solution on YOUR website!
(2x)3y - (2x)y = 6xy - 2xy = 4xy\r
\n" ); document.write( "\n" ); document.write( "The first answer, a), is equal to 4xy as well.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(2x)2y = 4xy\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The answer is a).
