Answer:x ≥+4
Explanation:
Remember in an earlier lesson, you learned about taking x by it's self.
You're doing the same thing here. 
(-10) x+14 ≥ 14 (-10)
 x≥ +4
Then you a dot on the +4 spot your line. and since this is an equal greater sign, you fill in the dot. Lastly you draw the arrow as it's been shown.
