\n" ); document.write( "Solve:
\n" ); document.write( " $\"2a+=+a\"$ and $\"a%2Bb+=+2\"$
\n" ); document.write( " $\"2a+=+8\"$ Divide both sides by 2.
\n" ); document.write( " $\"highlight%28a+=+4%29\"$
\n" ); document.write( " $\"a%2Bb+=+2\"$ Substitute $\"a+=+4\"$
\n" ); document.write( " $\"4%2Bb+=+2\"$ Subtract 4 from both sides.
\n" ); document.write( " $\"highlight%28b+=+-2%29\"$ \n" ); document.write( "

\n" );
