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

Putting the point in x+3y=22

7 + 3 (19) = 22\\7 + 57 = 22\\64 \neq 22

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.

A system of equations is shown below. Find the solution by using substitution.
ASHA 777 [7]

Answer:

a) (-2, 0)

Step-by-step explanation:

x + 2 = 3x + 6

-3x - 3x

___________

−2x + 2 = 6

- 2 - 2

_________

4 = −2x

_ ___

−2 −2

-2 = x [Plug this back into both equations above to get the y-coordinate of 0]; 0 = y

I am joyous to assist you anytime.
