I cant follow what you've written but here is the correct solution with steps:-

-5x - 14 = 2x + 7

-5x - 2x - 14 = 2x - 2x + 7

-7x - 14 = 7

-7x - 7 - 14 = 7 - 7

-7x - 21 = 0

-7x -21 + 21 = 21

-7x = 21

-7x/-7 = 21 /-7

x = -3 answer

Determine which measure of center best represents the best data. Explain.​
Monica [59]

Answer:

Step-by-step explanation:

I always like to use the mean if I can. In this data set, it's probably not a very good idea. Too much weight is given to that 7.2 and the two 3.2s.

I would choose the median, because the mode is the same answer and that's a good enough reason for choosing anything. 2 out 3 isn't bad as they say in Baseball.
