Question

Which equation can be used to represent "three minus the difference of a number and one equals one-half of the difference of three times the same number and four”?

(1 – n) – 3 = 6 plus 2 left-parenthesis x plus 4 right parenthesis equals StartFraction one-half EndFraction left-parenthesis 3 minus x right-parenthesis.(4 – 3n)
3 – (1 – n) = 6 plus 2 left-parenthesis x plus 4 right parenthesis equals StartFraction one-half EndFraction left-parenthesis x minus 3 right-parenthesis.(4 – 3n)
(n – 1) – 3 = left-parenthesis 6 plus 2 right-parenthesis left-parenthesis x plus 4 right parenthesis equals StartFraction one-half EndFraction left-parenthesis 3 minus x right-parenthesis.(3n – 4)
3 – (n – 1) = left-parenthesis 6 plus 2 right-parenthesis left-parenthesis x plus 4 right parenthesis equals StartFraction one-half EndFraction left-parenthesis x minus 3 right-parenthesis.(3n – 4)

Answer 1

(1-n)-3 = 1/2(3n-4)

Answer 2

3 minus the difference of a number and 1 would be (1-n)-3

One-half of the difference of three times the same number and four would be written as 1/2(3n – 4)

Set them to equal each other:

(1-n)-3 = 1/2(3n-4)
