I am to use interval notation for the solution set:
\n" ); document.write( "Please help
\n" ); document.write( "3x+9=3(x-3)
\n" ); document.write( "3x+9=3x-9
\n" ); document.write( "9=-9
\n" ); document.write( "Answer: the null set
\n" ); document.write( "--------------------
\n" ); document.write( "Here is another one:
\n" ); document.write( "3x<9 and 2x+1>3
\n" ); document.write( "x<3 and 2x>2
\n" ); document.write( "x<3 and x>2
\n" ); document.write( "(-inf,3)and(2,inf)
\n" ); document.write( "-----------
\n" ); document.write( "Cheers,
