Let R = Rollie's present age
\n" ); document.write( "Then Pollie's age is R - 7
\n" ); document.write( "Given: 3 years ago, Rollie was two times as old as Pollie, so we can write
\n" ); document.write( "R-3 = 2((R-7)-3)
\n" ); document.write( "R-3 = 2R-20
\n" ); document.write( "This gives R=17
\n" ); document.write( "So Rollie's age = 17 and Pollies age = 17 - 7 = 10
\n" ); document.write( "Check:
\n" ); document.write( "3 years ago their ages were 14 and 7:
\n" ); document.write( "14 = 2*7
\n" ); document.write( " \n" ); document.write( "
