For the system of linear algebraic equations:(adsbygoogle = window.adsbygoogle || []).push({});

x − y = 1

2x + 3y = 7

a) find solution by the Cramer’s rule;

b) find solution by the method of Gaussian elimination;

c) write the first iteration of the Jacobi method with the initial guess x^0=y^0=1.

I understand Cramer's Rule, and I think I understand Gaussian elimination, have got

x=2 and y=1 for both of them, but I have no idea how to do part c). Can anyone help me?
