First, distribute the 5 into (x+10)
This leaves you with the equation 5x + 50 - 10x = 100
From there, combine 5x and -10x together since they have the same variable
This gives you 50 - 5x = 100
Now you subtract 50 from both sides to get the x by itself
Now you have -5x = 50
Divide both sides by -5
This leaves you with the final answer: x = -10
Answer: The adverb slowly describes the verb walked. It basically says HOW the person walks (like did they walk fast, slow, at an average pace, etc., and in this case, it says that they walked in a slow manner).
Edit: so I’m assuming effect is like the mood of the story created, and I’d say that it creates a somber, suspenseful feeling, opposed to if she was walking quickly, which would create a rushed mood.
