There are arrows that go both ways, however there are o's that are blacked out, has either a diagonal line or an x going through the o's. What do they mean? Our text book does not explain much, it assumes that everyone is not a re-beginner with algebra.\r

Check \"worked problems\" in your text to see what

\n" ); document.write( "8x+8>7x+9
\n" ); document.write( "Substract \"8\" from both sides to get:
\n" ); document.write( " 8x> 7x+1
\n" ); document.write( "Substract \"7x\" from both sides to get:
\n" ); document.write( " x>1
\n" ); document.write( "Draw a number line; mark the zero; determine \"1\".
\n" ); document.write( "Draw an open circle at \"1\" to indicate it is not
\n" ); document.write( "part of the solution. Draw an arrow to the right
\n" ); document.write( "starting at the open circle. That is the graph
