Answer by TimothyLamb(4379)   (Show Source):
You can put this solution on YOUR website! w + k + v = 5871
v - k = 20
v - w = 28
---
v - k = 20
k = v - 20
---
v - w = 28
w = v - 28
---
v = 20 + k = v = 28 + w
20 + k = 28 + w
---
w + k + v = 5871
(v - 28) + (v - 20) + v = 5871
v - 28 + v - 20 + v = 5871
3v = 5919

Answer:
v = 1973
k = 1953
