The answer is 5,-2,-3 but i need with steps that make sense what is the solution to the system of equations? x+3y−z=2 4x+2y+5z=1 3x+z=12 (−1, 2, 3) (3, 0, 3) (5, −2, −3) (−4, 1, −3)

Select the correct answer from each drop-down menu. a system of equations and its solution are given below. system a complete the sentences to explain what steps were followed to obtain the system of equations below. system b to get system b, the equation in system a was replaced by the sum of that equation and times the equation. the solution to system b the same as the solution to system a.]
