Do the brackets first. $\"9-4%28-x%29=x-3\"$
\n" ); document.write( " $\"9-%28-4x%29=x-3\"$ multiply out by 4
\n" ); document.write( " $\"9%2B4x=x-3\"$ minus a minus is a plus
\n" ); document.write( " $\"9%2B3x=-3\"$ take away x from both sides
\n" ); document.write( " $\"3x=-12\"$ take away 9 from both sides
\n" ); document.write( " $\"x=-4\"$ divide both sides by 3 \n" ); document.write( "

\n" );
