Question

Solve the system using either Gaussian elimination with back-substitution or Gauss-Jordan elimination.If the system has an infinite number of solutions, express x₁, x₂, and x₃ in terms of the parameter t.)

2x_{1 +} 3x_{3 = 3}

4x_{1 -} 3x_{2 +} 7x_{3 = 1}

8x_{1 -} 9x_{2 +} 15x_{3 = 11}

(x₁, x₂, x₃) = ?
