Solve System of Equations with Python

If you’re looking to learn how to solve system of equations in Python, you’ve come to the right place. In this video tutorial, we’ll be using the sympy library module to solve the system of equations.

sympy is a powerful module that allows you to work with symbolic mathematics in Python. It provides a wide range of functionalities for algebraic calculations, and one of its key features is the ability to solve systems of equations.

In this tutorial, we’ll start by introducing you to the basics of the sympy library module and then move on to solving systems of equations. We’ll walk you through the step-by-step process of setting up your code and using the sympy library to solve the system of equations.

Python Code

  • equation 1 is 3x + 2y + z = 10
  • equation 2 is x + 4y + 2z =15
  • equation 3 is x + y + z = 8

import sympy as sp

# Define the variables
x, y, z = sp.symbols('x y z')

# Set up the equations
eq1 = sp.Eq( 3*x + 2*y + z, 10 )
eq2 = sp.Eq(x + 4*y + 2*z, 15)
eq3 = sp.Eq(x + y + z, 8)

# Solve the system of equations
solution = sp.solve((eq1, eq2, eq3), (x, y, z))

# Display the solution
print("x =", solution[x])
print("y =", solution[y])
print("z =", solution[z])
