Conclusion. The article explains how to solve a system of linear equations using Python's Numpy library. You can either use linalg.inv () and linalg.dot () methods in chain to solve a system of linear equations, or you can simply use the solve () method. The solve () method is the preferred way. # python # numpy NumPy has no concept of symbolic solutions. You can use SymPy as follows: from sympy import *a1, a2, a3 = 3, 4, 5 # known coefficients, they could be symbols toox1, x2, x3, x4, x5, x6 = symbols('x1:7')y1, y2, y3, y4, y5, y6 = symbols('y1:7')eqns = [a1*x1 - y1, a1*x2 - y2, a2*x3 - y3, a2*x4 - y4, a3*x5 - y5, a3*x6 - y6, x2 - y3, x3.
