Consider the homogeneous system given by ax + by = 0 cx + dy = 0 (a) Show that if (x0, y0) is a solution to this linear system, then so is (kx0, ky0) for any constant k. (b) Show that if (x0, y0) and (x1, y1) are solutions to this linear system, then so is (x0 + x1, y0 + y1).

(b) Confirm that $x_{1}=1, x_{2}=1, x_{3}=1$ is a solution of the nonhomogeneous system. (c) Use the results in parts (a) and (b) to find a general solution of the nonhomogeneous system. (d) Check your result in part (c) by solving the nonhomogeneous system directly.
