What would you need to multiply by in order to solve this system of equations using the linear combination (elimination) method?

6x-2y=4

7x+5y=3

A) Multiply the 1st equation by 3 and leave the 2nd equation alone. This will eliminate the y's when you add the two new equations together.

B) Multiply the 2nd equation by - 6 and leave the 1st equation alone. This will eliminate the x's when you add the two new equations together.

c) Multiply the 1st equation by 7 and multiply the 2nd equation by 4. This will eliminate the x's when you add the two new equations together.

D) Multiply the 1st equation by 5 and multiply the 2nd equation by 2. This will eliminate the y's when you add the two new equations together.
