x=8

Step-by-step explanation:

move the +2 to the right side so it can be subtracted by the 5 to get 3. after that you square both sides of the equation to get rid of the square root symbol. then move the -7 to the right side and add it with 9. then you'll have 2x=16. then divide both sides by 2 to get x by its self and you are left with x =8
