Solving Multiple Linear Equations With Numpy

Here we have solved the below Multiple Linear Equations using numpy:

𝑥+2𝑦−𝑧=42

𝑥+𝑦+𝑧=−2

𝑥+2𝑦+𝑧=2

Import Libraries

import numpy as np

Creating Array of values using numpy

# coefficient matrix 
A = np.array([[1, 2, -1], [2, 1, 1], [1, 2, 1]])

# numbers on the right without variables
b = np.array([4, -2, 2])

# solve using np.linagl.solve()
np.linalg.solve(A, b)

Output

array([-1.66666667, 2.33333333, -1. ])
