利用python求解线性方程组

原方程组为：2x+3y+z-7 && 3x+3y+2z-5

线性方程组形式为：Ax=b

A是形状为（m,n）的系数矩阵，b是常数向量

利用linsolve(system，*symbols)方法求解

import sympy as sp

x, y, z = sp.symbols('x, y, z')
system = [2 * x + 3 * y + z - 7, 3 * x + 3 * y + 2 * z -5]
sol = sp.linsolve(system, x, y, z)
print(sol)
A = sp.Matrix([[2, 3, 1], [3, 3, 2]])
b = sp.Matrix([7, 5])
system = (A, b)
sol = sp.linsolve(system, x, y, z)
print(sol)
system = sp.Matrix([[2, 3, 1, 7], [3, 3, 2, 5]])
sol = sp.linsolve(system, x, y, z)
print(sol)
