he coordinate grid shows the graph of four equations: A coordinate grid is shown from negative 12 to positive 12 on the x axis a
denis23 [38]

The set of equation that is known to have 5 and 0 as solutions is A and B.

<h3>How to solve for the system of equations.</h3>

From the graph that we have here in this question, we are supposed to identify the equations that have this point.

We can do this by tracing the lines in order to locate 5 and 0 on the grid.

When we trace the bine that has 5 and 0, We would find out that it is traceable to A and B.

What is the solution to the equation?<br><br> 6x-3=3x+12
Alla [95]

Answer:

x=5

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

6x−3−3x=3x+12−3x

3x−3=12

Step 2: Add 3 to both sides.

3x−3+3=12+3

3x=15

Step 3: Divide both sides by 3.

3x/3=15

x=5

denis23 [38]

we know that

If the point has an nonzero abscissa (x ​​coordinate) then it can be located in any of the four quadrants

If the point has an negative ordinate (y ​​coordinate) then it can be located in Quadrant III or Quadrant IV

therefore

the answer is the option

Quadrant III or Quadrant IV
