Hello :)
First, solve each side before we solve the inequality
4 − (x + 2)
−3x − 12
− (x+2)
4 − x − 2
*group the like terms*
− x + 4 − 2
− x + 2
−3(x + 4)
−3(x + 4)
3x − 12
− x + 2 < 3x − 12
subtract 2 from both sides
− x + 2 < −3x − 12
-2 -2
−x < − 3x − 14
add 3x to both sides
−x < − 3x − 14
+3x +3x
2x < − 14
divide both sides by 2

Answer:
19
Step-by-step explanation:
Adriana needs to send 232 invitations to her family and friends for her party.
There are 12 invitations in a box.
We need to find how many boxes will Adriana needs to order so that everyone receives an invitation. Let there are x boxes. It can be calculated as :
or
x = 19
So, she will need approx 19 boxes.
