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 = (4 – 3n) 3 – (1 – n) = (4 – 3n) (n – 1) – 3 = (3n – 4) 3 – (n – 1) = (3n – 4)

Answer 1

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

Answer 2

Let

n--------> the number

we know that

1) the expression "three minus the difference of a number and one" represent the equation

`3-(n-1)`

2) the expression "equals" represent the symbol

`=`

3) the expression "one-half of the difference of three times the same number and four" represent the equation

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

so

the complete expression, represent the equation

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

therefore

the answer is

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