   5N + 10D  =  90     

                N  =  D     

   5N + 10N  =  90     

            15N  =  90     

                N  =  6     

            &  D  =  6     

 

   check answer     

 

   Does (6 • 5¢) + (6 • 10¢)  =  90¢  ?     

               30¢    +    60¢       =  90¢     

                                    90¢  =  90¢  True
