How to solve this system of equations in sage?

$x_1+l_1x_2+l_1^2x_3+\dots+l_1^kx_k=c_1+r $.

$x_1+l_2x_2+l_2^2x_3+\dots+l_2^kx_k=c_2+r^2$

$\dots $

$x_1+l_kx_2+l_k^2x_3+\dots+l_k^kx_k=c_k+r^k$

where $l_i$'s are different positive integers and $c_i,r$ are integers in $[0,256]$

In particular, we can solve with sage. Here is the code :

a0, a1,a2,b3,b4, b5,r,l1,l2,l3 = var('a0,a1,a2,b3,b4,b5, r,l1,l2,l3')$
