Let's replace every copy of x with 7 and simplify.

Which is clearly false. This is probably the set of steps you followed to get "no solution".
Why is there no solution? Well let's subtract 9 from both sides to isolate the square root

Recall that the result of a square root operation is never negative. The range of
and
is the set of nonnegative numbers. There is no way we can have the left hand side result in -6
If there was a negative sign out front the square root and we have this instead

then the answer would be x = 7
Unfortunately, there isn't such a negative sign, so we stick with "no solutions".
Answer:The answer would be inclusive.
sorry it took me a while. Hope this helps!
Answer: I’m pretty sure it’s the 4th one.
Step-by-step explanation: because 1 and 2 have infinity solutions but 3 has no solution 4 comes up with x=-11
Can you give brainiest? :)
