Can't solve this for integer values

x + y = A
x + y*z = B

x,y,z = ? and x,y,z must be integers, A and B are known values and also integers. How to solve this.

Re: Can't solve this for integer values

Substituting, you have
y * (z - 1) = B - A

which means you just have to choose a factorization of B - A.
