Use five iterations of Jacobi’s method to find approximate solutions of the following system: -4x + y = 17 2x + 5y = 19 Take x 0 = 2, y 0 = -1. Consider the system 4x + y + z = 6  2x + 5y - z = 18 3x...

Use five iterations of Jacobi’s method to find approximate solutions of the following system: -4x + y = 17 2x + 5y = 19 Take x₀
= 2, y₀= -1.

Consider the system 4x + y + z = 6  2x + 5y - z = 18 3x - y + 6z = -6 (a) Use three iterations of Jacobi’s method to find an approximate solution to the given system. Takex₀
= 0, y₀
= 2, z₀
= 0  . (b) Repeat (a) using the Gauss–Seidel method.
