Answer 2

Answer:

12 years old

Step-by-step explanation:

lets take A for Alfie and F for Father.

Back in x years Alfie was:

A=18-x  years

Back in x years the Father was:

F=42-x  years

But the father's age must be 3 times Alfie's

F=3 x A

3(18-x)=42-x

54-3x=42-x

-2x=-12

x=6

Alfie will be: 18-6 = 12 years old

The father will be :42-6=36 years old
