lana [24]

Answer:

<em>A.  12x + 7y = 20  and B.  12x + 7y = 25 </em>

Step-by-step explanation:

I think you question is lack of key information, allow me to add more to fullfil your question

<em>A system of equations has no solution. If the given equation (12x+7y=16) is one of the equations in the system, which of the equations below could be the other?</em>

<em>A. 12x + 7y = 20 </em>

<em>B. 12x + 7y = 25 </em>

<em>C. 12x + 9y = 20 </em>

<em>D. 12x + 9y = 25 </em>

My answer:

A. 12x + 7y = 20  and B.  12x + 7y = 25  

Because the two linear system are parallel to each other, they have the same slope: y = -7/12 without any intersection.

Hope it will find you well.
