Solve the system of linear equations.(Enter your answers as a comma-separated list. If there is no solution, enter NO SOLUTION. If the system has an infinite number of solutions, set X3 = t and solve for x1 and X2 in terms of t.)

4x1 - 3X2 + 5X3 = 2
X1 + x2 - 2x3 = 3
3x1 - 4x2 + 7X3 = 9

(X1,X2,X3)=
