Answer: x < -44

Step-by-step explanation:

alright my fellow dude gamer, i want you to know that "a number" is basically just x

so lets do this

$\frac{1}{4}x + 13 < 2$

ok now we are going to solve for x, no?

$\frac{1}{4}x < -11$

i just subtracted 13 from both sides

now we divide -11 by 1/4

$x < -44$

MAGIC! ABSOLUTELY FANTASTIC! OH MY GOODNESS AHHHHHHH
