This does what you want: 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, b, c, d, e}] {{a -> 19/46, b -> 12/23, c -> 1/2, d -> 11/23, e -> 27/46}} Steve Luttrell "roger" <roger at banditorange.com> wrote in message news:chbm20$rnt$1 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.
