Solve for the linear system using Gaussian Elimination 2x1 + 6x2 + X3 = 7 X1 + 2x2 – X3 = -1 5x1 + 7x2 – 4x3 = 9

6. Solve the system of linear equations 2x₁ + 2x₂ + 4x3 16 4x₁ + 2x₂x3 = 6 -3x₁ + x₂ − 2x₂ = 0 a. by Gauss-Jordan elimination. b. by inverse method.

Find the set of solutions for the linear system -3x1 6x2 3x3 9. 672 8x3 -8 Use x3, x2, etc. for the free variables if necessary. Indicate if a variable is free by writing the same variable in the space (so if x1 is free, write x1 =x1). 2x2 - x3 - 3 4/3x3 - 4/3 x3 = x3

Solve the system using either Gaussian elimination with back-substitution or Gauss-Jordan elimination. (If there is no solution, enter NO SOLUTION. If there are an infinite number of solutions, set x3 = t and solve for X₁ and X2.) X1 - 3x3 = -5 3x1 + x₂ - 2x3 = 1 2x1 + 2x2 + x3 = 1 (X1, X2, X3) = Need Help? Read It ►
