The given composite function is:


\begin{gathered} (g\circ f)(x)=7 \\ \text{Which means} \\ g(f(x))=7 \end{gathered}

As we can see in the table, g(x)=7 when x=2, in this case the argument of g(x) is f(x), then f(x)=2. Again, in the table we find that f(x)=2 when x=1, then:


g(f(1))=g(2)=7

Then the solution is x=1:


(g\circ f)(1)=7
