Answer:

-3 < x

Explanation:

We solve inequalities just as we solve equations --- variables to one side and numbers to another and solve. Thus one note:

Whenever we multiply/divide by a negative number, we change (REVERSE) the inequality sign.

Let's solve this:


-18 < 5x - 3\\-18+3<5x\\-15<5x\\(-15)/(5)<x\\-3<x

This is kind of awkward because usually "x" (variable) stay to left side and number to right side. But doesn't MATTER!

We can read the solution as :

"x is greater than -3"

This can also be written as:

x > - 3

We can write in both ways. From answer choices, it is

" -3 < x "
