title: How to draw planes from a set of linear equations in Python?
body: <p>I have a linear system with three equations:</p>
  
  <blockquote>
    <p>x<sub>1</sub>- 2x<sub>2</sub> + x<sub>3</sub> = 0 <br> 2x<sub>2</sub>
    - 8x<sub>3</sub> = 8 <br>
    -4x<sub>1</sub> + 5x<sub>2</sub> + 9x<sub>3</sub> = -9</p>
  </blockquote>
  
  <p>The solution set is (29, 16, 3), which is a point at the intersection of these planes.</p>
  
  <p>Hoping if anyone can plot these planes in a 3D-space using Matplotlib to visualize the problem clearly.</p>
