Answer 1

$1.3.\\1)\ \ y_0=2\ \ ,\ \ y-|x-2|-2=0\ \ \to \ \ 2-|x-2|-2=0\ \ ,\\\\|x-2|=0\ \ \Rightarrow \ \ x-2=0\ \ \boxed {\ x=2\ }\\\\2)\ \ y_0=2\ \ ,\ \ 2y+|x+1|-3=0\ \ \to \ \ 4+|x+1|-3=0\ \ ,\\\\|x+1|=-1\ \ \Rightarrow \ \ \boxed{\ x\in \varnothing \ }\ ,\ \ tak\ kak\ \ |x+1|\geq 0$

$3)\ \ y_0=2\ \ ,\ \ 3y-(x+1)^2-3=0\ \ \to \ \ 6-(x+1)^2-3=0\ ,\\\\(x+1)^2-3=0\ \ \Rightarrow \ \ (x+1-\sqrt3)(x+1+\sqrt3)=0\ ,\\\\\boxed {\ x_1=-1+\sqrt3\ \ ,\ \ x_2=-1-\sqrt3\ }\\\\\\\\1.4.\ \ \ xy-3x=0\ \ \to \ \ \ \boxed {n=2}\ \ (xy\ \ \to \ \ 1+1=2)\\\\(2x-y)^2+x^2-5=0\ \ \to \ \ \ \boxed {n=2}\ \ \ (x^2)\\\\x^2y^2+xy=4\ \ \to \ \ \ \boxed {n=4}\ \ \ (x^2y^2\ \ \to \ \ 2+2=4)$
