7. Find all real values of h such that the system of linear equations 4.x + 7y = h x+ 3y = -1 -x - 5y = 5 is consistent. (Hint: Any solution of the system must, in particular, be a solution of the two equations that do not involve h. You can use this to answer the question without needing to row-reduce an augmented matrix.)
