Solve the system using either Gaussian elimination with back-substitution or Gauss-Jordan elimination. (If there is no solution, enter NO SOLUTION. If the system has an infinite number of solutions, express x1, x2, and x3 in terms of the parameter t.)
2x1 | + | 3x3 | = | 3 | ||
4x1 | − | 3x2 | + | 7x3 | = | 4 |
8x1 | − | 9x2 | + | 15x3 | = | 13 |
(x1, x2, x3) = ()
