x=63

Explanation:

x+1=8
Now you have to square both sides to cencle out root.

(x+1)2=82
x+1=64
x=641
x=63

In order to verify: 63+1=8
64=8
±8=8
In the verification ± is just because of the rule any number squared gives a positive value. Accordingly (8)2=64 as well as 82=64.

The previous answer was not correct.
