5x + 2y = 5 3x - y = 14 Which of the following equations is not a result of solving the system of equations by addition? 11x = 19 11x = 33 11y = -55

Respuesta :

Ukmmmmm

Answer:

11x = 19

Step-by-step explanation

5x + 2y = 5  and 3x - y = 14

5x + 2(3x -14) =5 and y = 3x -14

5x + 6x -  28 = 5 and  y = 3x -14

11x = 33  and y = 3x -14

x = 3 and y = 3 x 3 -14 = -5

11x =19 <=> x = 11/19 (F)

11x = 33 <=> x= 3 (T)

11y = -55 <=> x= -5 (T)
