What is a possible first step to eliminate a variable in the following system? 2x – 3y = –1 3x – 4y = –3 Multiply the first equation by –3 and the second equation by 2. Multiply the first equation by 3 and the second equation by –2. Multiply the first equation by –4 and the second equation by 3. All of the above.

So that would mean the first part of the answer will be -3, but then I don't understand how the second part can be 2 because there isn't a 2 in the second equation?
