If we have the Blanchard Kahn error, can we move the time?

Hi Dear All
If we have the Blanchard Kahn error, can we move the time?
For example, we have 12 eigenvalue(s) But we have 10 forward-looking variable(s)

One of our equations is as follows:
A=B
Can we write: A(+1)=B(+1)??
In this case, the problem may be solved.
The question is, if the model is solved by this manipulation, will it have a bad effect on the results?
