Find all solutions to the system

$$\begin{array}{rcrcr}-3 x_1 & + & x_{2} & = & 0 \\6 x_1 & - & 2 x_{2} & = & -3\end{array}$$

by eliminating one of the variables.

$(x_1,x_2) =$

Help: If there is a solution $(a,b)$, enter your answer as a point (a,b). If there is a free variable in the solution, use s1 to denote the variable $s_1$. If there is no solution, type no solution.
