2. Eliminasi Gauss 2.3 Eliminasi Gauss-Jordan

Solution

9. Dengan menyelesaikan variabel utama terhadap variabel bebas,

diperoleh

x 1 = −3x 2 − 4x 4 − 2x 5

x 3 = −2x 4

x 6 = 1 3

10. Tetapkan nilai sebarang untuk variabel bebas, misal

x 2 = k, x 4 = l, x 5 = m, maka diperoleh solusi

x 1 = −3k − 4l − 2m x 4 = l

x 2 = k

x 5 = m

x 3 = −2l x 6 = 1 3
