I need to know what x equals

Thank you for the opportunity to help you with your question!

hey, this question is not clear. Is 2x-1 or 2x+1

2x+1 is in the square root as well as x+4

okay,

so square both sides to get 2x+1-1=x-4

simplifying we get 2x=x-4

taking like terms together, 2x-x=4

then x= -4 is the solution
