\n" ); document.write( "C = 3CJ
\n" ); document.write( "ten years from now the sum of
\n" ); document.write( "their ages will be 28.
\n" ); document.write( "C + 10 + CJ + 10 = 28
\n" ); document.write( "Replace C with 3CJ from top equation.
\n" ); document.write( "3CJ + 10 + CJ + 10 = 28
\n" ); document.write( "Collect like terms:
\n" ); document.write( "3CJ + CJ = 28 - 10 - 10
\n" ); document.write( "4CJ = 8
\n" ); document.write( "CJ = 2
\n" ); document.write( "....................
\n" ); document.write( "CJ is currently 2 years old
\n" ); document.write( "Chemany is currently 6 years old.
