Let x = Father's age now
Let y = Daughter's age now
given:
(1) +x+=+5y+
(2) x+%2B+6+=++3%2A%28y+%2B+6%29+
-------------------
There are 2 equations and 2 unknowns, so it's solvable
By substitution:
(2) 5y+%2B+6+=++3%2A%28y+%2B+6%29+
(2) 5y+%2B+6+=+3y+%2B+18+
(2) 2y+%2B+6+=+18+
(2) 2y+=+12
y+=+6
and
(1) x+=+5y
x+=+30
The Father is 30 and the daughter is 6
