4 (!). Solve the systems of equations:
1) \(\left\{\begin{array}{l}x^{2}-2 x=0 \\ x^{3}+y=6\end{array}\right.\)
2) \(\left\{\begin{array}{l}y^{2}-4 y+3=0, \\ 2 x+y=9 .\end{array}\right.\)
4. 1) 0 and 6 or \(2 \cdot\) and -2 . Hint. Solve the combined system of equations:

\[
\left\{\begin{array} { l } 
{ x = 0 } \\
{ x ^ { 3 } + y = 6 , }
\end{array} \text { or } \left\{\begin{array}{l}
x=2, \\
x^{3}+y=6
\end{array}\right.\right.
\]
2) 4 and 1 or 3 and 3 . Hint. Solve the combined system of equations:

\[
\left\{\begin{array} { l } 
{ y = 1 , } \\
{ 2 x + y = 9 , }
\end{array} , \text { or } \quad \left\{\begin{array}{l}
y=3 \\
2 x+y=9
\end{array}\right.\right.
