The least common denominator is 5y, and can be obtained by multiplying
-1/y by 5/5 to get -5/5y.

If we add the numbers using the least common denominator, we get:
-5/5y + 2/5y = -3/5y

Which of these strategies would eliminate a variable in the system of equations ?

Answer:

Step-by-step explanation:

I believe the answer is B because if we multiply the top equation by 6, we get 48x + 30y = -42, and if we multiply the bottom equation by -5, we get

35x - 30y = 20. So now, if we add it all together, then the positive 30y and negative 30y cancel out aka it equals 0, and thus the variable y is gone, satisfying the requirement that the problem asks for ("Which of these strategies would eliminate a variable...").

I hope this helped, and if it's correct, I'd appreciate if you marked my answer as Brainliest :)
