To solve the inequality, you need to isolate/get the variable "x" by itself in the inequality:

-4x < 20      Divide -4 on both sides to get "x" by itself

[tex]\frac{-4x}{-4} <\frac{20}{-4}[/tex]   when you multiply/divide a negative number to both sides of the inequality, you have to flip the inequality sign

x > -5

Your answer is the 4th option
