It is given in the question that
Ben has a collection of 812 stamps. He gives his brother 345 stamps.
And we have to find how many stamps does Ben have left .
Let x stamps are left.
So we have
![x+345=812](https://tex.z-dn.net/?f=x%2B345%3D812)
Subtracting 345 from both sides
![x+345-345 = 812-345](https://tex.z-dn.net/?f=x%2B345-345%20%3D%20812-345)
![x = 467](https://tex.z-dn.net/?f=x%20%3D%20467)
Therefore after giving 345 stamps to his brother, 467 stamps are left .
