Answer:

[tex]x \geqslant 3[/tex]

[3, infinity)

Step-by-step explanation:

-3n + 4 < n-8

get all of the n's to the same side

-3n + 4 < n-8

+3n + 4 < +3n-8

4 < 4n-8

send the number (-8) off to the other side

4 < 3n-8

+8< 3n +8

12 < 3n

isolate variable

12/3 < 3n/3

4 < n

so

[tex]x \geqslant 3[/tex]
