Solve the system of equations. If the system has no solution, say that it is inconsistent. Graph the lines of the system. \( \begin{array}{l}3 x+y=3 \\ 6 x+2 y=-3\end{array} \) Select the correct choice below and, if necessary, fill in any answer boxes within your choice. A. The solution is \( x=\square \) and \( y=\square \). (Type integers or simplified fractions.) B. There are infinitely many solutions. Using ordered pairs, they can be expressed as \{( \( x, y \) ) \( \mid x=\square \), \( y \) is any real number \( \}. \) (Simplify your answer. Type an expression using y as the variable as needed.) C. The system is inconsistent.

Use the Gauss-Jordan method to solve the following system of equations. \[ \begin{array}{r}3 x-4 y+4 z=10 \\ 3 x+5 y-z=15 \\ 12 x-7 y+11 z=45\end{array} \]

Data la retta di equazione \( (k-1) x+3 y-2=0 \), determina \( k \) in modo che: a) la retta sia parallela alla retta \( y+2=0 \); b) la retta sia parallela alla retta \( x-3 y=0 \); c) la retta sia perpendicolare alla retta \( x+2 y=0 \); d) la retta passi per \( P(-2 ; 1) \).
