Father 7

Father is six times older than his son. After four years, the father will only be four times older. What are their present ages?

Correct result:

f =  36
s =  6

Solution:


f=6s
f+4 = 4(s+4)

f=6•s
f+4 = 4•(s+4)

f-6s = 0
f-4s = 12

f = 36
s = 6

Our linear equations calculator calculates it.
