There was once a number $\"x\"$
\n" ); document.write( "That number was multiplied times $\"3\"$
\n" ); document.write( "After that, to the product they added the number $\"6\"$
\n" ); document.write( "We know something about the result, but we want to go back to $\"x\"$
\n" ); document.write( "We need to undo what was done to $\"x\"$
\n" ); document.write( "undoing each operation in the reverse order than they were done.
\n" ); document.write( "So the result of all that is more than $\"5%7D%7D%0D%0A%7B%7B%7B3x%2B6%3E5\"$
\n" ); document.write( "Before they added the $\"6\"$ it was
\n" ); document.write( " $\"3x%2B6-6%3E5-6\"$ or $\"3x%3E-1\"$
\n" ); document.write( "And before that, before they multiplied by 3 it was
\n" ); document.write( " $\"3x%2F3%3E-1%2F3\"$ or $\"x%3E-1%2F3\"$
\n" ); document.write( "Positive and negative numbers can be put on a number line, just like positive and negative numbers for temperature are on the scale of the outdoor thermometer on my back patio.
\n" ); document.write( " $\"number_line%28+600%2C+-10%2C+10%29%2C%0D%0Acircle%28+-1%2F3%2C+0%2C+0.2+%29\"$
\n" ); document.write( " $\"x%3E-1%2F3\"$ means that x is not $\"-1%2F3\"$
\n" ); document.write( "but it could be any number greater than that, meaning any number on the number line to the right of $\"-1%2F3\"$
\n" ); document.write( "It is often represented by coloring the portion of the number line to the right of $\"-1%2F3\"$
\n" ); document.write( "and drawing a circle around $\"-1%2F3\"$
\n" ); document.write( "like this:
\n" ); document.write( "

\n" ); document.write( "If the result had been $\"x%3E=-0.3\"$ $\"x=-1%2F3\"$
\n" ); document.write( "would also be a solution, and that would be indicated by coloring in the circle. \n" ); document.write( "

\n" );
