The best possible first step to solving
5x – 7y = –4
3x – 10y = –14 by eliminating the x, would be to multiply the first equation by 3 and multiply the second equation by 5, right?

alexwee123 · Answer

there are many "best" ways to solving problems
the best way is the way that you like the most and find the easiest to use XD
