Best ResponseYou've already chosen the best response.6solve equations with inequality instead of equal sign is very similiar, only have to worry about sign changing operations

Best ResponseYou've already chosen the best response.6only difference is if u multiply both of them by 1 , then what was greater will be more negative

Best ResponseYou've already chosen the best response.6the same way you solve normal equations, only remember how multiplication by negative number changes it

Best ResponseYou've already chosen the best response.6solve for n like you do a normal equation, keep track of the number of times you multiply by a negative number

Best ResponseYou've already chosen the best response.6if the number of times you multiply by a negative number is odd, then you flip sign else u keep the sign oriented same way

Best ResponseYou've already chosen the best response.6ya, u have to have n all by itself

Best ResponseYou've already chosen the best response.621k 3n + 9p > 3p + 12 okay so we saw how adding and subtracting will keep the inequality, as everything just gets shifted left or right

Best ResponseYou've already chosen the best response.621k 3n + 9p > 3p + 12 so subtract 21k from both side and 9p

Best ResponseYou've already chosen the best response.6what do you think we should to now?

Best ResponseYou've already chosen the best response.6u can go the other way too u can add 3n to both sides as well as subtract 3p and 12 from both sides 21k 3n + 9p > 3p + 12 21k + 9p 3p  12 > 3n notice in this case it automatically takes care of the sign flip
