oh you will want to solve one equation for one variable and then plug that into the second equation to get the solution. 
x=-3.07921 and y=9.36634

i dont get it

You have the 2 equations, and then you isolate x in the first, and insert the value in the 2nd equation. Now you have 1 equation with 1 variable, then you isolate y in that equation. Now you have the answer for y, and you can insert that in one of the equations and isolate x.

If you do that, then you should get
$$x=311/101$$
and
$$y=946/101$$

 The 2 functions look like this: (the place they cross is also the answer)
