How do you solve  log (x+7)=1?

I tried this:

Explanation:

It depends upon the 'base" of your log. Let us say that is $10$; we can write:

${\log}_{10} \left(x + 7\right) = 1$

using the definition of log we can write:

$x + 7 = {10}^{1}$

and:

$x = 10 - 7 = 3$

if you have a different base use the one you got instead of $10$.
