How to evaluate system of equations in Sympy? -

i have next scheme of equations

from sympy.abc import x,y,z sympy import solve, eq eqs = [eq(x,y), eq(y,z)] result = solve(eqs, x)

now want able substitute value z , evaluate x. how can that?

you should include 2 variables want solve after eqs , proceed follows:

>>> result = solve(eqs, x, y) >>> result[x].subs(z,42) 42
