Use Gaussian elimination with backward substitution and two-digit rounding arithmetic to solve the following linear systems. Do not reorder the equations. (The exact solution to each system is x₁ = -1, x₂ = 1, x3 = 3.) b. 4x₁2x₂ Xx3 = -5, x₁ + x₂x3 = -1, x₁ + 4x₂ + 2x3 = 9. -

Solve the following system of linear equations: 5x2-5x3 = -5 x1+2x₂-5x3 = -1 If the system has infinitely many solutions, select "The system has at least one solution". Your answer may use expressions involving the parameters r, s, and t. The system has no solutions
