Let e = evan
\n" ); document.write( "Let Cody=2e
\n" ); document.write( "Eight years ago, e+c=8
\n" ); document.write( " $\"%28e-8%29%2B%282e-8%29=8\"$
\n" ); document.write( "Associative and commutative and definition of subtraction
\n" ); document.write( " $\"e%2B2e-8-8=8\"$
\n" ); document.write( "Add 16 to both sides
\n" ); document.write( " $\"e%2B2e=24\"$
\n" ); document.write( " $\"3e=24\"$
\n" ); document.write( " $\"e=8\"$
\n" ); document.write( "Evan is 8 and Cody is 16. \n" ); document.write( "

\n" );
