$\"x\"$ = number of days until Jane's birthday
\n" ); document.write( " $\"4x%2B8\"$ , which is 8 more than 4 times $\"x\"$ ,
\n" ); document.write( "is the number of days until Ray's birthday,
\n" ); document.write( "and that number is $\"24\"$ .
\n" ); document.write( "So, your equation is
\n" ); document.write( " $\"4x%2B8=24\"$ .
\n" ); document.write( "The number that is $\"x\"$ is what you want to find,
\n" ); document.write( "but it has been wrapped up
\n" ); document.write( "in that expression to the left of the equal sign.
\n" ); document.write( "First, $\"x\"$ was multiplied times $\"4\"$ ,
\n" ); document.write( "and then for a second layer of wrap, $\"8\"$ was added to that.
\n" ); document.write( "To unwrap $\"x\"$ , you start by removing the outer layer,
\n" ); document.write( "the one that was applied last.
\n" ); document.write( "So, you add a $\"-8\"$ to both sides.
\n" ); document.write( "(If you want, you could say you are subtracting $\"8\"$ from both sides).
\n" ); document.write( "You get $\"4x%2B8-8=24-8\"$ ,
\n" ); document.write( "which simplifies to $\"4x=16\"$ .
\n" ); document.write( "Then, you undo the multiplication times $\"4\"$
\n" ); document.write( "by dividing both sides of the equal sign by $\"4\"$ to get
\n" ); document.write( " $\"4x%2F4=16%2F4\"$ , which simplifies to $\"highlight%28x=4%29\"$ .
\n" ); document.write( "There are $\"highlight%284%29\"$ days until Jane's birthday. \n" ); document.write( "

\n" );
