\n" ); document.write( "p = 2c
\n" ); document.write( " Seven years ago the sum of their ages were 31.
\n" ); document.write( "(p-7) + (c-7) = 31
\n" ); document.write( "p + c - 14 = 31
\n" ); document.write( "p + c = 31 + 14
\n" ); document.write( "p + c = 45
\n" ); document.write( " Find their ages now
\n" ); document.write( "replace p with 2c
\n" ); document.write( "2c + c = 45
\n" ); document.write( "3c = 45
\n" ); document.write( "c = 45/3
\n" ); document.write( "c = 15 is Chris's age

\n" ); document.write( "p = 2(15)
\n" ); document.write( "p = 30 is Pete's age
