cool I'm doing this too
so this is what u do for:
y = -x + 4
-5x + 2y = -6
first of all you replace the 2y with the (-x+4) and you and add the x's which would be -6x, then you subtract the -6 in the equation by the 4 and you should get -10 of course, so u devide the -10 by the -6x and u should get the value of x, and then u solve for y in the beginning now knowing what x is.
I don't know if i did this wrong, you should ask your teacher, but I'm doing pretty good in this so far but I fell like I missed something like dividing the numbers in the first equation by 2 for 2y in the second equation before adding them
