Question 833570
You can't solve this fully without an actual value, but here's the way to do it.
Let m be dad and x be son
m+10 = 3x
.
Let's say the son is 12.
m+10 = 3*12
m = 36-10 or 26 (highly improbable!)
.
The son is more likely older; let's say 20
m+10 = 60
m = 60 - 10 = 50
That makes more sense.
