Respuesta :
Let
n--------> the number
we know that
1) the expression "three minus the difference of a number and one" represent the equation
[tex]3-(n-1)[/tex]
2) the expression "equals" represent the symbol
[tex]=[/tex]
3) the expression "one-half of the difference of three times the same number and four" represent the equation
[tex]\frac{1}{2}(3n-4)[/tex]
so
the complete expression, represent the equation
[tex]3-(n-1)=\frac{1}{2}(3n-4)[/tex]
therefore
the answer is
[tex]3-(n-1)=\frac{1}{2}(3n-4)[/tex]
