You can put this solution on YOUR website!
Let +x+ = the number of jellybeans Jon started with
After eating 1/3 of them, there are +%282%2F3%29%2Ax+ left
After eating 1/4 of what is left, there is +%283%2F4%29%2A%282%2F3%29%2Ax+ left
+10+ were left, so
+%283%2F4%29%2A%282%2F3%29%2Ax+=+10+
Multiply both sides by +12+
+6x+=+120+
+x+=+20+
There were 20 jellybeans to start with
------------
check:
Started with 20
ate 1/3, or 20/3
There are 40/3 left
Ron ate 1/4 or 10/3
There are 10 left
