The correct answers are:
- The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.
- The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.
Further explanation:
Given equations are:
2x-y = -5
x+3y = 22
We have to check whether the given statements are true or not. In order to find that we have to put the points in the equations
Putting the point in 2x-y = -5
![2x - y = -5\\2(7) -19 = -5\\14-19 = -5\\-5 = -5](https://tex.z-dn.net/?f=2x%20-%20y%20%3D%20-5%5C%5C2%287%29%20-19%20%3D%20-5%5C%5C14-19%20%3D%20-5%5C%5C-5%20%3D%20-5)
Putting the point in x+3y=22
![7 + 3 (19) = 22\\7 + 57 = 22\\64 \neq 22](https://tex.z-dn.net/?f=7%20%2B%203%20%2819%29%20%3D%2022%5C%5C7%20%2B%2057%20%3D%2022%5C%5C64%20%5Cneq%2022)
The point satisfies the first equation but doesn't satisfy the second. So,
1. The ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.
This statement is true as the point satisfies the first equation
2. The ordered pair (7, 19) is a solution to the second equation because it makes the second equation true.
This Statement is false.
3. The ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.
This statement is true.
4. The ordered pair (7, 19) is a solution to the system because it makes both equations true.
This statement is false as the ordered pair doesn't satisfy both equations.
