Is this laptop good enough for general use and low graphic games?

Should be fine for low performance. I shudder at the thought of using a lenovo product again

AMD is generally weaker than you think, with performance lower than expectations. Refurbished without a good warranty just means used and cleaned.
As a cpu, FX-7500 is about on a par with i3-5020U or 6006U, below i3-6100U by 17%

In graphics, here it shows the FX-7500 R7 underperforms Intel HD 520 by 21%

This agrees, where you can also see gaming reports:

It is very slightly better in CPU and Graphics than a i3-5020U

curry's seems on clearance and is competitive at this level.
The value of new-equivalent of that laptop is about £360 or so.
Priced at 75% of new-equivalent, it is approximately priced right.

£380 to £430 is the typical cost of a new general purpose everyday use, economical but not junk - trash- rubbish level. The performance of what you show is just a little lower. As long as you understand what you are getting without any higher expectations, it is good enough. With so many people overestimating and expecting more than it really is, I have only tried to show you what that laptops is for a "compared to new" level.

Yes.
