Tao uses elimination to solve the following system of linear equations. negative 2 x plus 4 y is equal to 16 2 x plus 2 y is equal to 8 Which ordered pair is the solution to the system?

Add the equations −2x + 4y = 16 and 2x + 2y = 8 to eliminate x. This gives 6y = 24, so y = 4. Substitute y = 4 into 2x + 2y = 8 to get 2x + 8 = 8, so x = 0. The solution is (0, 4), choice B.
