let the son's age be x
then father's age = 30 + x
in 19 years, the father will be 3 times as old as his son,
(x+19) × 3 = 30 + 19+ x
3x + 57 = 49 + x
3x - x + 57 - 49 = 0
2x + 8 = 0
x = -8/2
x = - 4
I think there's something wrong with your question.
i shouldn't get the answer in negative since its age
