 Question : write a system of linear equation representing any physical phenomena 

                                                            〖7x〗_1+〖6x〗_2+〖3x〗_3=19

                                                                         3x₁+2x₂ - x3 = 7

                                                                   x₁ + 4x₂ + 2x₃ = 19

(i)                  Solve the system by analytical method(gauss elimination /cramer’s/LUfactorization)    

(ii)                Solve the system by numerical method(Jacobi)                                                         

(iii)               Compare the answers.
