Which statements are true about the ordered pair (10, 5) and the system of equations? (Look at the file to answer the question)

Answers:

The first and third options should be selected.

Explanation:

In order for a point to be a solution to a system of equations, it must make both equations true when its x and y values are substituted in. That being said, we need to test if (10,5) is a solution for the two equations.

Let's try the first equation. Substitute 10 for x and 5 for y and solve:

-5 does equal -5, so (10,5) is a solution to the first equation.

Next, let's test the second equation. Do the same:

However, 20 does not equal 11, therefore (10,5) is not a solution to the second equation.

So far, we know that (10,5) is a solution to the first equation, but not the second equation. Knowing this, it cannot  be a solution to the system because it does not make both equations true. Therefore, only the first and third options should be selected.
