Solve the system of linear equations below. Enter your solution as an ordered pair (x,y). Do not include spaces in your answer.

2x + y = -1
x - 2y = 7

I got the order pair of (0,3). Am I correct? If not please explain how then I can figure it out myself. Please & thank you! :D

$(0,3)$ does not work
look at the first equation
if you put $x=0$ and $y=3$ you get $2\times 0+3=-1$ which is not right
