We thank F. Csikor, G. Egri, I. Montvay and A.A. Tóth for their help and suggestions. This work was partially supported by Hungarian Scientific grants, OTKA-T37615/T34980/T29803/M37071/OMFB1548/OMMU-708. For the simulations a modified version of the MILC public code was used (see http://physics.indiana.edu/~sg/milc.html ). The simulations were carried out on the Eötvös Univ., Inst. Theor. Phys. 163 node parallel PC cluster.

N2 - In this Letter we give the equation of state of QCD at finite temperatures and densities. The recently proposed overlap improving multi-parameter reweighting technique is used to determine observables at nonvanishing chemical potentials. Our results are obtained by studying nf = 2 + 1 dynamical staggered quarks with semi-realistic masses on Nt = 4 lattices.
