$\"3X+%2B+%28X+%2B+7%29+=+2X+-+-11\"$
\n" ); document.write( "Simplify the equation
\n" ); document.write( " $\"4X+%2B+7+=+2X+%2B+11\"$
\n" ); document.write( "Subtract 2X from both sides
\n" ); document.write( " $\"2X+%2B+7+=+11\"$
\n" ); document.write( "Subtract 7 from both sides
\n" ); document.write( " $\"2X+=+4\"$
\n" ); document.write( "Divide both sides by 2
\n" ); document.write( " $\"highlight%28X+=+2%29\"$ \n" ); document.write( "
