Let Emily's age = +x+
Emma's age is +x+%2B+6+
---------------------------------
Emily's age in 3 yrs = +x+%2B+3+
Emma's age in 3 yrs = +x+%2B+6+%2B+3+
-------------------------------------------
given:
+x+%2B+6+%2B+3+=+2%2A%28+x+%2B+3+%29+
+x+%2B+9+=+2x+%2B+6+
+x+=+3+
and
+x+%2B+6+=+9+
-----------------------
Emma is 9 now
--------------------
check:
+x+%2B+6+%2B+3+=+2%2A%28+x+%2B+3+%29+
+9+%2B+3+=+2%2A%28+3+%2B+3+%29+
+12+=+12+
OK
