Step-by-step explanation:

I could help!!!
Please just tell me the questions and I would do my best :)
S = 3/5 or 0.6
explanation
-4/0.8 = 2/s-1
divide the numbers on the left: -5 = 2/s-1
multiply both side by s-1: -5(s-1)=2
simplify: -5s + 5 =2
gather like terms: -5s= 2 - 5
simplify: -5s= -3
divide both sides by -5: x=3/5
