The Father will always be 25 year older than his Son
Let +f+ = Father's age now
Let +s+ = Son's age now
given:
(1) +f+=+s+%2B+25+
(2) +f+=+3s+%2B+7+
By substitution:
+s+%2B+25+=+3s+%2B+7+
+2s+=+18+
+s+=+9+
and
(1) +f+=+s+%2B+25+
(1) +f+=+9+%2B+25+
(10 +f+=+34+
The Father's age is 34
The Son's age is 9
