Ben is seven more than two times as old as Denise. In 15 years the sum of their age will be 76. How old is Denise now?

Question

Lost on this one. Can someone please help me with this one. Thank you

Answer 1

B - Ben's age

 

D - Denise's age

 

   B = 7 + 2D 

 

   

     D +15 + 7 + 2D + 15 = 76

 

      3D = 39

 

  D = 13  

 

 B = 7 + 2( 13) = 33
