please help me, I got the answer wrong and I don't what to do

Answer:
x = 124
Step-by-step explanation:
Firstly yu can move the 6 to the other side...where the equation would be in this form
; fifth root of ( 249 - 2x) = 7 - 6
; fifth root of ( 249 - 2x) = 1
; 249 - 2x = 1^5
; 2x = 248...,then divide both sides by 2
; Hence..., x = 248/2
