One ionization step is enough; the pH is very high, near one K. The 2nd step is negligible. I bet the teacher wants 2 ICE boxes, not one. Plus, I'm getting 2 unknowns. I think I'm missing something.

Some of the HCO3- will bond with water and form OH- and H2CO3 again. This is an equilibrium. But If we have only one HCO3- that didn't yet bonded to water and formed H2CO3 again, we will have more H+ in the medium, and it will be acid.
