Explanation:

let's break it down first


4x + 8 < 20


4x < 20 - 8


4x < 12

Divide both sides by the coefficient of x which is 4


4x / 4 < 12 / 4


x < 3


4 < x < 3

4 is less than x which is greater than 3

x = 4,5,6,7,8,......

since 4 is less than x, x cannot be 4

so x could be 5,6,7,8,9,.......
