What's the problem? eqns = {5*a - c - d - e == 1/2, 4*b - c - e == 1, 6*c - a - b - d - e == 1, 4*d - a - c == 1, 5*e - a - b - c == 3/2}; Solve[eqns] {{a -> 19/46, c -> 1/2, d -> 11/23, e -> 27/46, b -> 12/23}} David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: roger [mailto:roger at banditorange.com] To: mathgroup at smc.vnet.net 5a-c-d-e =0.5 4b-c-e =1 6c-a-b-d-e=1 4d-a-c =1 5e-a-b-c =1.5 Solve for a,b,c,d, and e. Guass inversion isnt working. Maybe a matrix solution.
