Interactive Problem 407: LSE without Parameters


A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

Solve the following linear system of equations:

\begin{displaymath}
\begin{array}{rcrcrcc}
2x_1 & & & + & x_3 & = & 1 \\
2...
...x_3 & = & 1\\
6x_1 & + & 3x_2 & & & = & -1\\
\end{array}
\end{displaymath}

Solution: not specified

The LSE has

$ \rule[-0.5ex]{0pt}{2ex}$ no solution .
$ \rule[-0.5ex]{0pt}{2ex}$ exactly one solution ,
$ \rule[-0.5ex]{0pt}{2ex}$ infinitely many solutions ,
$ \rule[-0.5ex]{0pt}{2ex}$ $ \rule[-0.5ex]{0pt}{2ex}$ $ \rule[-0.5ex]{0pt}{2ex}$
$ \rule[-0.5ex]{0pt}{2ex}$ namely $ x_1=$ , $ \rule[-0.5ex]{0pt}{2ex}$ $ x_2=$ , $ \rule[-0.5ex]{0pt}{2ex}$$ x_3=$ .
$ \rule[-0.5ex]{0pt}{2ex}$ namely $ x_1=r$, $ \rule[-0.5ex]{0pt}{2ex}$ $ x_2=$ $ r$, $ \rule[-0.5ex]{0pt}{2ex}$$ x_3=$ $ r$.

Specify the solution rounded on three decimal places if it is necessary.
