Let A = Marty's age
\n" ); document.write( "Let B = Mickey's age
\n" ); document.write( "--------------
\n" ); document.write( "Equation 1: $\"A+=+35\"$
\n" ); document.write( "Equation 2: $\"5B+=+A+%2B+20\"$
\n" ); document.write( "Plug 35 into equation 2 for A
\n" ); document.write( "Equation 2: $\"5B+=+A+%2B+20\"$
\n" ); document.write( " $\"5B+=+%2835%29+%2B+20\"$
\n" ); document.write( " $\"5B+=+55\"$
\n" ); document.write( "Divide both sides by 5
\n" ); document.write( " $\"highlight%28B+=+11%29\"$
\n" ); document.write( "Mickey is 11 years old \n" ); document.write( "

\n" );
