Question

-27 greater than or equal to 3x-9

How do you solve this? Taking a refresher course and need some help to jog my memory

Answer 1

add nine to both sides to get -18>or=to 3x then divide both sides by three to get -6>or= to x

Answer 2

add 9 to what? the 3x and the -9 or the -27?

Answer 3

He said...."to both sides" .. The whole idea in algebra is that you always do the same thing to both sides to keep the equality.

Answer 4

-27 >= 3x - 9 --- add 9 to both sides
-27 + 9 >= 3x - 9 + 9 -- combine like terms
- 18 >= 3x -- divide both sides by 3
-18/3 >= 3x/3
-6 > x

do you understand ?
