4x5y+z=105x4y2z=9x+3y+2z=12 How many solutions are there to this system? A. None B. Exactly 1 C. Exactly 2 D. Exactly 3 E. Infinitely many F. None of the above If there is one solution, give its coordinates in the answer spaces below. If there are infinitely many solutions, enter the parameter t in the answer blank for z, enter a formula for y in terms of t in the answer blank for y and enter a formula for x in terms of t in the answer blank for x. If there are no solutions, leave the answer blanks for x,y and z empty. x= y=
