title: How do constraint optimization in OrTools with coefficents?
body: <p>I want to use ortools to generate all the possible combinations of a simple problem as in the following program. In this case I want x and y to be multiplications of 5 and additionally if start is 7, then the values of the x should be 7, 10, 15, 20, 25 and so on. How can I change following code for this?</p>
  
  <pre><code>  model = cp_model.CpModel()
  
    start = 7
    end = 20
    x = model.NewIntVar(start , end - 1, "x")
    y = model.NewIntVar(start , end - 1, "y")
    # Create the constraints.
    model.Add(x != y)
  </code></pre>
