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”?

  3 - (n -1) = (1/2)(3n -4)

Step-by-step explanation:

three minus the difference of a number and one: 3 - (n -1)

one-half of the difference of three times the same number and four: (1/2)(3n -4)

These two expressions are said to be equal, so the equation is ...

  3 - (n -1) = (1/2)(3n -4)

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
