Four years ago, Val was 5 times as old as Daniel was then. 8 years from now, Val will be twice as old as Daniel will be then. Find the age of each now.

Question

solve 

Answer 1

v - 4 = 5(d - 4)

v + 8 = 2(d + 8)

 

v - 4 = 5d - 20

v + 8 = 2d + 16

 

v = 5d - 16

v = 2d + 8

 

5d - 16 = 2d + 8

3d = 24

d = 8

 

v = 2(8) + 8

v = 16 + 8

v = 24

 

Daniel is 8 and Val is 24
