Select the ordered pair that is a solution of the system of linear equations.
Pachacha [2.7K]

Answer:

the ordered pair will be (1, 2)

Step-by-step explanation:

first of all substitute the x and y values into the equation in other to make the equation true.

Therefore y=4x-7

1 = 4(2) -7

1 = 8 -7

1 = 1

Making the first equation true. then move to the second equation which is y = - x + 3

1 = -(2) + 3

1 = 1
