Question

How do you solve the inequality `-6.1n>3.9n +5`?

Answer 1

n < `-1/2`

Explanation:

collect like terms : - 6.1n - 3.9n > 5
so - 10n > 5

     now multiplying or dividing an inequation by a negative value 
     requires the inequality sign to be reversed

hence n < `5/-10`

and simplifying gives n< `- 1/2`
