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


(-4x)/(-4) <(20)/(-4) 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
