Question 1030015: Don had 9 packets of toffos. He gave 2 packets to Emma, who also had 25 loose toffos. They discovered that they then had exactly the same amount of toffos. Make an equation to show this information( let x be the number of todos in 1 packet) and then solve the equation to determine how many toffos are in 1 packet.

You can put this solution on YOUR website!
Let x be the number of todos in 1 packet.
+9+-+2+=+7+ is what Don had after giving 2 to Emma
+7x+ = toffos that Don ended up with
+2x+%2B+25+ = toffos that Emma ended up with
-------------------
+7x+=+2x+%2B+25+
+5x+=+25+
+x+=+5+
----------
There are 5 toffos in 1 packet
--------------------------
check:
+7x+=+7%2A5+
+7x+=+35+
and
+2x+%2B+25+=+2%2A5+%2B+25+
+2x+%2B+25+=+35+
OK
