Ms. W has 400 followers on Twitter and is gaining 75 followers each day. Mrs. Hill has 1,000 followers on Twitter, but is losing 25 followers a day. How many days will it take them to have the same number of followers?

It takes 6 days.

Step-by-step explanation:

First, you have to form expressions for both of them in terms of x. Let x be the number of days :

Ms. W = 400 + 75x

Mrs. Hill = 1000 - 25x

Next, you have to compare it as we want to find out how many days in takes for them to have the same number of followers :

400 + 75x = 1000 - 25x

75x + 25x = 1000 - 400

100x = 600

x = 6
