Re: [Axiom-math] (no subject)

[Martin Rubey]

solve([x*y + a*x^2 = 10, x-y = 2], [x,y])

                           2
   (5)  [[x= y + 2,(a + 1)y  + (4a + 2)y + 4a - 10= 0]]
                         Type: List List Equation Fraction Polynomial Integer

(However, these are really polynomial equations...)
