You can put this solution on YOUR website!
ok first off.. if it is a Linear equation then it is always = . example. x+y=0
\n" ); document.write( "there is no way it can be changed in to an inequality. example. x+y<0\r
\n" ); document.write( "\n" ); document.write( "if it an EQUATION it is always =
\n" ); document.write( "if it is an INEQUALITY it is <, >, < or = to (< with a line under it), > or = to(> with a line under it). An inequalit can never just be =\r
\n" ); document.write( "\n" ); document.write( "i really hope this helps you
