Hello,

How can I solve a system of equations to obtain the following coefficients a1, a2, a3 and a4 using the Symbolics.jl package.

I know that it is possible using the SymPy package, but I am interesting in solving it using Symbolics.jl

I have made the following example:

julia> eq1

4-element Vector{Num}:

a1 == 1

a2 == 0

(a1 + La2 + a3(L^2) + a4*(L^3)) == 0

(a2 + 2La3 + 3a4(L^2)) == 0

I would like to solve the above system to obtain the expression for a1, a2, a3 and a4.

I know that the solution should be this:

a1 => 1

a2 => 0

a3 => -3/L^2

a4 => 2/L^3

Is it possible to solve the system of equations so the coefficients are returned as a vector?

I hope that this post is okay!
