Can someone please work out this equation step by step for me? I keep getting my math wrong somewhere. The correct answer is -2.

$$\sqrt{3x+10} = \sqrt{x+11} - 1$$

anonymous · Answer

Let me try it really quickly

anonymous · Answer

Okay! Thank you!

anonymous · Answer

Ok so I got negative 2 but I got another answer with it....x=5

anonymous · Answer

Anyone want to confirm that with me?

anonymous · Answer

I have no idea what the heck I did wrong. Let me go back over my math.

anonymous · Answer

Well I mean I was asking more so if they gave another answer since like I said I got another answer with the -2

anonymous · Answer

No, it just says -2 is the only answer.

anonymous · Answer

Let me recalculate it a different way to see what I get

anonymous · Answer

Okay.
