PPT-Solving homogeneous equations: Ax = 0

Putting answer in parametric vector form Isabel K Darcy Mathematics Department Applied Math and Computational Sciences University of Iowa Fig from knotplotcom Solving homogeneous equations Ax 0 . Lesson Objective:. An equation is like a set of scales.. To keep it balanced, whatever you. do to one side you must do to the other.. Use this idea to solve equations like:. 3x + 1 = x + 7 . 2 (3x + 1) = 3 (x – 2). using Elimination. Steps:. 1. Place both equations in Standard Form, A. x . + B. y . = C.. 2. Determine which variable to eliminate with Addition or Subtraction.. 3. Solve for the variable left.. Multiplication . Equations. 3-3 Solving . Multiplication . Equations. Solve. Solution. GOAL. Find the value of the variable that makes the. equation TRUE.. The value that makes the equation true.. To isolate the variable (have the variable on one. 21. (. 5-. 6. ).
