Answer:
[tex]\huge\boxed{B. [1,2,3,........]}[/tex]
Step-by-step explanation:
[tex]9x - 4 < 13 x - 7[/tex]
Combining like terms
=> [tex]-4 + 7 < 13x-9x[/tex]
=> [tex]3 < 4x[/tex]
Dividing both sides by 4
=> [tex]x > \frac{3}{4}[/tex]
=> [tex]x > 0.75[/tex]
This means that x can be any number that is greater than 0.75
So, The solution set = [1,2,3,........]
