Answer:

x > 3

Step-by-step explanation:

The inequality to solve is:

5 - 4x < - 7

We will solve this using same method as solving an equation. We will take numbers to one side and variables to another and multiply and divide accordingly.

So,

[tex]5-4x<-7\\5+7<4x\\12<4x\\\frac{12}{4}<x\\3<x[/tex]

That means "x is greater than 3", so we can write:

x > 3
