Which Equation Means That 7 Less Than Twice A Number Is 1 class=

Sagot :

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)
