You can put this solution on YOUR website!
x*y = x*y ... reflexive property (any number is ALWAYS equal to itself)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x*y = 2*5 ... substitution property (ie you're replacing x with 2 and y with 5 on the right side)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x*y = 10 ... multiplication\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So it sounds like the answer is substitution
\n" ); document.write( "
\n" );
