Using a sample of 1.8 million D[overline D] mesons collected at the psi(3770) with the CLEO-c detector, we study the semileptonic decays D0-->pi-e+nue, D+-->pi0e+nue, D0-->K-e+nue, and D+-->[overline K]0e+nue. For the total branching fractions we find [script B](D0-->pi-e+nue)=0.299(11)(9)%, [script B](D+-->pi0e+nue)=0.373(22)(13)%, [script B](D0-->K-e+nue)=3.56(3)(9)%, and [script B](D+-->[overline K]0e+nue)=8.53(13)(23)%, where the first error is statistical and the second systematic. In addition, form factors are studied through fits to the partial branching fractions obtained in five q2 ranges. By combining our results with recent unquenched lattice calculations, we obtain |Vcd|=0.217(9)(4)(23) and |Vcs|=1.015(10)(11)(106), where the final error is theoretical.
