Hi every body:

how can i solve this equations(without numerical method):

eq1 := (D[1, 1](eta11))(t, a*t, a^2*t)+1.326096634*10^8*Pi^2*eta11(t, a*t, a^2*t)-3.315241586*10^7*Pi*eta21(t, a*t, a^2*t) = 0

eq2 := 2.054901810*10^13*eta21(t, a*t, a^2*t)+(D[1, 1](eta21))(t, a*t, a^2*t)-8.219607239*10^13*Pi*eta11(t, a*t, a^2*t)+4.137421500*10^8*Pi^2*eta21(t, a*t, a^2*t) = 0

eq3 := (D[1, 1](eta31))(t, a*t, a^2*t)+4.137421500*10^8*Pi^2*eta31(t, a*t, a^2*t) = 0
