the first one

jojo4eva · Answer

just substitue it in and it works

mathmale · Answer

2x – 5y = –10 could be solved for y:  5y=(2x+10) => y=(2x+10)/2.
Then you could substitute the x value from each of the given options until you find the one that produces the corresponding y value.  Faster.

Jon:  Does that constitute intelligent discourse?  What's your point?  Go elsewhere if you must insult people.
