We have studied two-body charmless hadronic decays of B mesons into the final states ππ, K π, and KK. Using 3.3 million BB pairs collected with the CLEO-II detector, we have made the first observation of the decays B⁰→ K+π-, B+→ K⁰π+, and the sum of B+ → π+π⁰ and B+ → K+π⁰ decays (an average over charge-conjugate states is always implied). We place upper limits on branching fractions for the remaining decay modes.
