If the system of linear equations 7 x+11 y+α z=13; 5 x+4 y+7 z=β; 175 x+194 y+57 z=361 has infinitely many solutions, then α+β+2 is equal to:
If the system of linear equations
$$\begin{aligned}
& 7 x+11 y+\alpha z=13 \\
& 5 x+4 y+7 z=\beta \\
& 175 x+194 y+57 z=361
\end{aligned}
$$
has infinitely many solutions, then $\displaystyle \alpha+\beta+2$ is equal to:
