    so we have 8 ≥ 3x + 5 and we want to isolate x, what is the first thing you would want to do?

    not quite, you want to first simplify the whole numbers, (8 and 5), to do this, without changing the equation, you can subtract 5 from both the left and right sides, so- 8 - 5 ≥ 3x + 5 - 5 so this simplifies to 3 ≥ 3x

    What do you think would be the next step to isolate x?

    okay um...I really want to say divide it from the 3 but I'm most likely wrong.

    no, thats actually correct! You want to divide both sides by 3. so you get 3/3 ≥ 3x/3 which simplifies down to 1 ≥ x

    Oh, well then. So if it's that simple what's with the two sentence thing?

    I think you're meant to draw the number line graph representing your answer and just a line or two explaining what the answer means exactly

    so try drawing up a line graph and describing your solution in a line or two

    Okay seems a bit pointless to do all that but alright. Thank you for your help.
