Solution
To solve this system of equations using the Gauss-Seidel method, we first rewrite the system in a form that allows iterative calculations for , , and . The given system of equations is:
Step 1: Rearrange Equations for Gauss-Seidel Iteration
To apply the Gauss-Seidel method, we isolate each variable in terms of the other variables on the right side. This gives us iterative equations as follows:
-
From the first equation, solve for :
-
From the second equation, solve for :
-
From the third equation, solve for :
Step 2: Choose Initial Guesses
To start the iteration, we need an initial guess for , , and . Typically, we start with:
Step 3: Perform Iterations
We will now substitute these initial guesses into the equations and iterate until the values converge within a certain tolerance (for instance, ).
Iteration 1:

Iteration 3 (and continue until convergence)
We continue this process, recalculating , , and at each step. Each subsequent iteration brings the values closer to the solution. Typically, after 4-5 iterations, the values stabilize within a small tolerance.
Conclusion
After a sufficient number of iterations (usually 5-10 for convergence within tolerance), we arrive at values for , , and that approximate the solution to the system.
Would you like further iterations, a summary, or additional help on a specific step?
Here are five follow-up questions to expand understanding:
