\n" ); document.write( "x = brother's age 5 years ago
\n" ); document.write( "x+4 = sister's age 5 years ago
\n" ); document.write( "(x+4)+22 = x+26 = father's age 5 years ago\r

\n" ); document.write( "\n" ); document.write( "Five years ago their father was twice as old as the sum of the ages of the children
\n" ); document.write( "father's past age = 2(brother's past age + sister's past age)
