*INFO TO ANSWER THE QUESTION:
The roof lines of a building can be described by the system of equations below, where the floor is represented by the x-axis and the y-axis and the height of the building is along the z-axis. Measurements are in feet. Find the point of intersection of the roof lines, using an ordered triple in the form (x, y, z).
x+y+z=53
3x−2y+z=69
−x+2y–z=−59
Answer is (5,-2,50)
