anonymous · Answer

elect the best possible first step to solving the following system by first eliminating the x variable.

5x – 7y = –4
3x – 10y = –14

Multiply the first equation by 3 and multiply the second equation by 5.

Multiply the first equation by –3 and multiply the second equation by 5.

Multiply the first equation by –3 and multiply the second equation by –5.

Multiply the first equation by 4 and the second equation by 14.
