You can put this solution on YOUR website!
Do both problems =7?
\n" ); document.write( "2n-3n=?
\n" ); document.write( "2a-3a=7
\n" ); document.write( "You can subtract them,becuase they are like terms;
\n" ); document.write( "2a-3a=7
\n" ); document.write( "-a=7
\n" ); document.write( "No you do not want to leave x as negative, so you need to divide each side by -1;
\n" ); document.write( "\"-a%2F-1\"=\"7%2F-1\"
\n" ); document.write( "a=-7
\n" ); document.write( "If the first equation =7, you would solve it the same way.
\n" ); document.write( "=)
\n" ); document.write( "
\n" );
