With the variable in the argument of the log function we need to rewrite the equation in exponential form to \"get at\" the x.
\n" ); document.write( " $\"log%282%2C+%282x%2B2%29%29+=+4\"$
\n" ); document.write( " $\"2x+%2B+2+=+2%5E4\"$
\n" ); document.write( " $\"2x+%2B+2+=+16\"$
\n" ); document.write( "Now we have a very simple equation to solve.
\n" ); document.write( "Subtract 2 from both sides:
\n" ); document.write( " $\"2x+=+14\"$
\n" ); document.write( "Divide both sides by 2:
\n" ); document.write( " $\"x+=+7\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
