multiply second equation by 4. Solve then.

I would use substitution because it's pretty much given to you y=2x+6

OpenStudy (anonymous):

Method choice is less important than mastering one and learning to use / apply it.

does y=-7?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

well what does x=?

OpenStudy (anonymous):

13/-2 or -6.5
