Answer:
Ray's present age is 12; and
Sam's present age is 36
Step-by-step explanation:
Let the son's present age=x
Sam is three times as old as his son Ray.
Therefore, Sam's age =3x
Their ages four years ago are:
Four years ago, Sam was 4 times his son Ray’s age.
Therefore:
Sam's age =4*Ray's age
3x-4=4(x-4)
Open the brackets
3x-4=4x-16
Collect like terms
4x-3x=16-4
x=12
Therefore:
Ray's present age is 12; and
Sam's present age is 3*12=36
