4. Because of the coat color

Explanation:

If calico cats are female because of the color of their coats are determined by the X chromosome, then it comes to reason as the Y chromosome to be dominating seeing as the X chromosones are responsible for being the leading factor of the cat's sex. (I'm sorry if this is a sucky answer and I have no idea what the answers are to the rest but I hope this helps at least a little bit)

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
