Hey there! So because this is to many question rolled in one, Im only going to be answering your simplify questions.
Starting with
1:
2:
3:
4:
So i solved this by using our square root functions. For if you didn't know, the square root symbol is this: √
Hope this helps!
Perhaps you miswrote the question because in your second equation there is no x variable. However, I inferred that you meant to write -4x+y=1, and was able to solve this system of equations. You can do this either by the substitution method or the graphing method, of which I used the latter. The solution to this system of equations is (0,1). Best wishes! c:
