Which equation means that 7 less than twice a number is -1?

From the problem statement:

n = "a number"

seven less than twice a number is -1

* now i'll underline the changes made by interpreting the way the question was written:

7 less than two times n is -1

7 less than 2*n equals -1

take away 7 from 2n = -1

2n take away 7 = -1

2n - 7 = -1

2n - 7 = -1

answer is:  (A)

bc thats onyl if everthign is equal but most thing r not that ballenced so probably one side will have more then the other :)
