Solve the system of equations 5x+3z & = 1, -x + y + z & = 0, 3y + 2z & = 5. if there is a solution, write it as an ordered triple of integers or common fractions in simplest form. for example, if x=1, y=6/4, and z=-4 were a solution, you would enter (1,3/2,-4). if there is no solution, enter the word "none" as your answer.
