Hi! Could somebody tell me how to solve(numerically) this system of equations in Mathematica for Di and De 0.135 == -0.34 Erf[0.0620537/Sqrt[De]]+0.34 Erfc[0.0340564/Sqrt[Di]]-0.34 Erfc[0.0368221/Sqrt[Di]] 0.0132 == -0.34 Erf[0.119209/Sqrt[De]]+0.34 Erfc[0.0654242/Sqrt[Di]]-0.34 Erfc[0.0707372/Sqrt[Di]] I have tried using FindRoot, NSolve and Reduce but couldnt get a solution which satisfies both equations. Thanks, Raj
