Ill give brainlist on whoever gets right

tina wrote the equations 3 x minus y = 9 and 4 x + y = 5. what can tina conclude about the solution to this system of equations?
(–3, 2) is a solution to the system of linear equations.
(–2, 3) is a solution to the system of linear equations.
(2, –3) is a solution to the system of linear equations.
(3, –2) is a solution to the system of linear equations.

(2, –3) is a solution to the system of linear equations.

Step-by-step explanation:

3x - y = 9

4 x + y = 5.

Add the equations

7x = 14

x = 2

Substitute it back into either original equation to find x

3(2) - y = 9

6 - y = 9

y = -3

4(2) + y = 5.

8 + y = 5

y = -3

x = 2

y = -3

(2, -3)

(2, –3) is a solution to the system of linear equations.

im not sure

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
