gimana cara menyelesaikan menggunakan eliminasi gauss jordan x^1 + x^2 + 2x^3 = 8 -x^1 - 2x^2 + 3x^3 = 1 3x^1 - 7x^2 + 4x^3 = 10

4x³ + 2x² + 2x = 16
4x³ - 7x² + 3x = 10
______________-
9x² - x = 6


6x³ + 3x² + 3x = 24
6x³ - 4x² - 2x = 2
______________-
7x² + 5x = 22


9x² - x = 6 *(7)
7x² + 5x = 22 *(9)


63x² - 7x = 42
63x² + 45x = 198
______________-
38x = 156
x = 156 / 38 = 4(2/19)
