Answer:

The one at the bottom

Step-by-step explanation:

Plug in the value of x = 3 for every equation

I plugged the value of 3 into this equation:

2(3) +3y = 0

3 + 2y = -1

Let's start with the first line

6 + 3y = 0

-6 -6

3y = -6

3y/3 = -6/3

y = -2

Now let's solve the second line

3 +2y = -1

-3 -3

2y = -4

2y/2 = -4/2

y=-2

Since both equations have the solution y = -2, that means the system of equations is valid when the value of x is 3.
