Identify the volume of the composite figure. The figure shows a rectangular prism with a cube removed. The prism is 9 meters long, 8 meters wide, and 3 meters high. The cube has a side of 4 meters.

The answer is "The ordered pair (-1,5) is a solution to the system because it makes both of the equations true."

to solve this, plug the values of the variables into each equation

(-1,5)    x = -1    y = 5

x + y = 4  

-1 + 5 = 4

4 = 4

the ordered pair is a solution to the first equation

x - y = -6

-1 - 5 = -6

-6 = -6

the ordered pair is a solution to the second equation

For an ordered pair to be a solution to a system, it must makes ALL the equations in the system true (which it did in this case); therefore, the ordered pair is a solution. Hope this helps!
