You can put this solution on YOUR website!
Let +n+ = number of years until
dad is twice as old as Pam
------------------------
+37+%2B+n+=+2%2A%28+14+%2B+n+%29+
+37+%2B+n+=+28+%2B+2n+
Subtract +28+ from both sides
+9+%2B+n+=+2n+
Subtract +n+ from both sides
+9+=+n+
In 9 yrs, Pam's dad is twice Pam's age
------------------
check:
In 9 yrs, Pam is: +14+%2B+9+=+23+
In 9 yrs, Pam's dad is: +37+%2B+9+=+46+
+46+=+2%2A23+
OK
