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)

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)
