It's been a while since I've done this and I wanna to know if my answers are correct. So I'll use whatever answers you provide and my reference. Thanks in advance. Here goes:

Solve the system. There are three different systems.
If the system has infinitely many solutions, express your answer in the form "X = X" and "Y" as a function of "X".

Your answer is: X=_____ and Y=_____.

1st System.
-x + y = 0,
4x - 3y = -3

2nd System.
3x + 2y = 6,
x - 2y = -6

3rd System.
2x - 6y = 2,
-3x + 9y = -3


My sister and I thank you all in advance for helping us. Mainly her. =)

I am building guitars, but I'd like to know how to go about buiding an electric cello; info on either that or the construction of the classic cello (as in Cremona, etc.) would be very good as well given that tructurally I can easily figure out the electric cello -after all, it IS based on the electric guitar and bass-, but the actual details concerning scales, etc., nut size, bridge, tailpiece, etc. are something I simply cannot afford to waste time figuring out on. These details would be explicite on plans for any type of cello.
