The function `solve`

aims at finding solutions *symbolically*, and it seems that Sage is not able to do it for your equation. If you want to solve your equation *numerically*, you can use `find_root`

as follows:

```
sage: find_root(1/3*x + sin(2*x)-1,0,1)
0.49428348982550824
sage: find_root(1/3*x + sin(2*x)-1,1,2)
1.261800196654962
```

as follows:

~~sin(2*x) - 1, 0, 1)

sage: find_root(1/3*x + ~~sin(2*x)-1,1,2)
~~sin(2*x) - 1, 1, 2)
