Answer 1

the answer is the number 3

Answer 2

I think the correct answer from the choices listed above is the second option. The first step to solving the system by first eliminating the x variable would be to multiply the first equation by –2 and multiply the second equation by 3. By doing so, when the two equations are added then x would be eliminated.
