Answer 1

@Directrix ?

Answer 2

\(\large\color{black}{ \sqrt{x+9}-4=1 }\)

add 4 to both sides.

Answer 3

@SolomonZelman i'm pretty sure it's 16, solution is extraneous

Answer 4

if you add 4 to both sides, raise both sides to the 2nd power, and then subtract 9 from both sides, you get the answer.

it is not 16.

Answer 5

it's not 16. can we do it together?

Answer 6

I'm thinking it is x = 34, not extraneous but the work will decide.

Answer 7

\(\large\color{black}{ \sqrt{x+9}-4=1 }\)
start from adding 4 to both sides, tell me, what do you get?
