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
