Best ResponseYou've already chosen the best response.1B) 2x  8y = 16(multi eq1 with 2) 2x  3y = 16 subtracting both eqs 5y = 0 y=0 x= 8 (8,0)

Best ResponseYou've already chosen the best response.1E) x  y = 2 3x  y = 0 subtracting both eqs 2x=2 x= 1 y=3 (1,3) yes E has solution set (1,3)

Best ResponseYou've already chosen the best response.1C)2x +2 y = 8(multi with 2) 3x + 2y = 2 subtract both eqs 5x=10 x= 2 y=2 (2,2) C has solution set (2,2)

Best ResponseYou've already chosen the best response.1D) 4x + 6y = 12 4x + 6y = 18(multi by 2) subtract both eqs 0 = 30 so D has infinite solutions
