Solve the following system of equations. Enter the y-coordinate of the solution. Round your answer to the nearest tenth. 5x+2y=7 -2x+6y=9 Thank you to anyone who can solve this, really.

OpenStudy (daniellelovee):

is this by any chance elimination?

OpenStudy (daniellelovee):

if that is the case then just eliminate and you'll get (12/17,59/34) meaning 59/34=y=1.7

OpenStudy (anonymous):

I'm not sure exactly :-\ I had (0.7,1.7) as an answer but the they said that the numerical entry was invalid

OpenStudy (anonymous):

Oh! So the answer would just be 1.7?
