Plug in 8 for x and -3 for y in both equations, and see if it makes the equations true.

First equation:
<span>
7x + 4y = 44

7(8) + 4(-3) = 44

56 - 12 = 44

44 = 44

The ordered pair works in the first equation.

Second equation:

3x - y = 27

3(8) - (-3) = 27

24 + 3 = 27

27 = 27

The ordered pair works in the second equation too.

</span>Since the ordered<span /> pair satisfies both equations, the ordered pair is a solution to the system of equations.

Answer is A)

26 cartons.
355 books / 14 books per carton = 25.36
Because you cannot ship a half carton, you would need a total of 26.
