3x - 8 > 22
Step-by-step explanation:
" eight less" means to subract 8 form something. If you had 10 apples and I took some so now you had 8 less apples, you'd have 10 - 8 = 2 apples
"three times a number" means 3x. 3 times some number.
The expression 3x - 8 means "8 less than 3 times a number"
"is" is math is a statement of equality, either an equals sign or an inequality needs to go here.

3x - 8 > 22
