Jeremy is twice as old Randy now. 6 years ago, the sum of their age was 18. How old is Jeremy now?     

 

J  =  2R                            (eq 1)     

(J – 6) + (R – 6)  =  18     (eq 2)     

 

substitute 2R wherever you see J in (equation 2)     

 

(2R – 6) + (R – 6)  =  18     

     2R – 6 + R – 6  =  18     

                3R – 12  =  18     

                        3R  =  30     

                          R  =  10     

 

from (eq 1)         J  =  2R    

                           J  =  2 10     

                           J  =  20
