You can put this solution on YOUR website!
Jim is +x+ yrs old in 2 yrs
His sister will be +2x+ yrs old in 2 yrs
--------------------
His sister is +2x+-+2+ yrs old now
-----------------------------------
check answer:
The difference in their ages is always:
+2x+-+x+=+x+ yrs ( the difference in 2 yrs )
----------------------
Now, the difference is:
+%28+2x+-+2+%29+-+%28+x+-+2+%29+
+2x+-+2+-+x+%2B+2+=+x+
OK
