Please help me I AM STUCK, and please explain how you get the answer.

Answer:
x= -10
Step-by-step explanation:
(3)8+ [tex]\frac{\sqrt{2x+29} }{3}[/tex]= 9(3) (multiply both sides by 3)
24+ [tex]\sqrt{2x+29}[/tex]= 27 (move the 24 to the right)
[tex]\sqrt{2x+29}[/tex]=27-24 (subtract)
([tex]\sqrt{2x+29}[/tex])²= 3² (square both sides)
2x+29=9 (move the 29 to the other side)
2x=9-29 (subtract)
2x= -20 (divide both sides by 2)
x= -10
hope this helps and good luck! :)
