Best ResponseYou've already chosen the best response.0one 7(less than or equal sign) 2X+3 two 2X+3(<)5 you will get two answers it would look like this for example 6<x>9

Best ResponseYou've already chosen the best response.0I end up with 2 is less than or equla to x

Best ResponseYou've already chosen the best response.0you should get 10 since you subtracted 3 and you have a 7 on the other side you get 10

Best ResponseYou've already chosen the best response.07 (less than equal) 2X+3 3 3 =10 (less than equal) 2x

Best ResponseYou've already chosen the best response.0your interval notation sould look something like this its a bad drawing, and than draw the arrows (left or right)

Best ResponseYou've already chosen the best response.0The solution would then look x<1 for the other one

Best ResponseYou've already chosen the best response.1if you started with 7 ≤ 2x+3 < 5 you should get, after simplifying, 5 ≤ x < 1 in interval notation, this is [5,1) the square brackets indicates 5 is part of the interval. ) means the upper value is a limit, approached but not reached.
