(1 point) Use matrices to solve the given system of linear equations. -2x 10 y - 25 z = + 9y + 212 = + 5 y + 12 z If there is one solution, give its coordinates in the answer spaces below. If there are infinitely many solutions, enter "2" in the answer blank for z, enter a formula for y in terms of z in the answer blank for y and enter a formula for a in terms of z in the answer blank for c. If there are no solutions, enter "none" in each of the blanks. y =
