The line $$\(x+y=7\)$$ is drawn on the grid. Use your graph to solve these simultaneous equations. $$\[ \begin{aligned} x+y & =7 \\ y & =2 x+1 \end{aligned} \]$$ $$\[ \begin{aligned} & x=\ldots \ldots \ldots \ldots \ldots \ldots . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . \\ & y=\ldots . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . \end{aligned} \]$$
