Use Gaussian elimination with backward substitution to solve the following linear system: 2x1 + x2 – x3 = 5, x1 + x2 – 3x3 = -9, -x1 + x2 + 2x3 = 9;arrow_forward
- 4. Use the Gauss-Siedel method to approximate the solution of the following system of linear equations. (Hint: you can stop iteration when you get very close results in three decimal places.) 5х1 — 2х2 + 3хз = -1 — 3х1 + 9х2 + хз — 2 2x1 – x2 – 7x3 = 3arrow_forward24. Solve the system.
