Answer:


D

Step-by-step explanation:

Here, we want to compare the equation of two lines

Let us take a look at the options:

a) This is incorrect. If we multiplied the first equation by 5, what we should have is equal to 25

b) This is incorrect. If we multiplied through by 2, what we should have is 2x + 2y = 10

c) This is incorrect. What we have on both sides for both equations must differ by a multiple

d) This is correct. There is no way to multiply either equation by a number to equal the other equation.
