pfenn1 · Answer

The first would be $$3x-8$$The second would be$$3(x-8)$$Less than implies subtraction.

anonymous · Answer

but which one i wirte correctly $$3x-8         or        8-3x$$

The first expression you wrote implies that you are looking at a number which is 8 less than three times the number.  The second implies you are looking at a number 3x less than the number 8.  What do you think?
