Solve for a:
\n" ); document.write( " $\"abs%284a%2B7%29+%3C+13\"$ Remove the absolute-value bars and write the two resulting inequalities:
\n" ); document.write( " $\"4a%2B7+%3C+13\"$ and $\"4a%2B7+%3E+-13\"$ Now solve each one of these inequalities.
\n" ); document.write( " $\"4a%2B7+%3C+13\"$ Subtract 7 from both sides.
\n" ); document.write( " $\"4a+%3C+6\"$ Divide both sides by 4.
\n" ); document.write( " $\"highlight%28a+%3C+6%2F4%29\"$ or $\"highlight%28a+%3C+3%2F2%29\"$
\n" ); document.write( "-------------
\n" ); document.write( " $\"4a%2B7+%3E+-13\"$ Subtract 7 from both sides.
\n" ); document.write( " $\"4a+%3E+-20\"$ Divide both sides by 4.
\n" ); document.write( " $\"highlight%28a+%3E+-5%29\"$
\n" ); document.write( "Notice that you get two answers when solving inequalities such as this.
