Best ResponseYou've already chosen the best response.1Hello @GalacticPlunder :) Sorry for the slightly late response :/ first we should try to get the absolute values alone on one side so I suggest dividing both sides by 2 first :) can you do that?

Best ResponseYou've already chosen the best response.0So it world be: x2 = 6. Then if I add two it would be x = 8 right? My teacher said there should be two answers though. I don't know what that means :/

Best ResponseYou've already chosen the best response.1it's just saying that for example if x = 2 then if can be split up into two equations: x = 2 and x = 2 this way: x  2 = 6 can be split up into x  2 = 6 and x  2 = 6

Best ResponseYou've already chosen the best response.1the absolute value means that anything inside it comes out as a positive value absolute value of +2 =  2  = 2 and   2  = 2 so if a "variable" is in the absolute value, there can be two answers (one for the positive/normal idea, and one for the negative idea)

Best ResponseYou've already chosen the best response.0Also this was added: "let's say you had a solution of x>2. How would you show this on a number line"

Best ResponseYou've already chosen the best response.1you would start on \(2\) :P then if the inequality > < thing has a line under it, it would mean \(include~the~number\) and be a dark circle (not the hollow one I drew) if the wider part of the > is facing the variable like \(x>\) that means you should shade the numbers Bigger than the given number

Best ResponseYou've already chosen the best response.0What is a literal equation? How is solving a literal equation different from solving a one or twostep equation?

jigglypuff314

Best ResponseYou've already chosen the best response.1A literal equation is an equation that is made up of all letters [variables] for example: \(A=b*h\) The difference between a one or twostep equation and a literal equation is that in a one or twostep equation, the aim (usually) is to get a numerical answer (a number as the answer). But for a literal equation, solving for a variable simply rearranges the original equation. Sorry if that's a little confusing, here's a link about literal equations that describes it better :) http://www.purplemath.com/modules/solvelit.htm
