Guided Practice Choose the ordered pair that is a solution of the system.

x + y = 4

x = –1

A.
(–1, 3)

B.
(5, –1)

C.
(–1, 5)

C.

(–1, 5)

Step-by-step explanation:

(− 1  , ​5) is a solution of the system because it makes both equations true. The ordered pair, negative 1, 5, is a solution of the system because it makes both equations true.

x + y− 1+54=?⎯⎯⎯⎯=444 X plus y equals 4.Does negative 1 plus 5 equal 4?Negative 4 equals negative 4.

x−1==−1−1 ✔ X equals negative 1.Negative 1 equals negative 1.
