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

1 - s = s - 4 (s=2.5)

Step-by-step explanation:

If you write the equation down, you get 3-(s-1) = 3(s-4), which (when you divide each side by 3), gives you -s+1=s-4. If you add s to both sides, you get 1 = 2s - 4, and after adding 4, you get 2s = 5, and s = 2.5

both equations and proportions are better.
