Best ResponseYou've already chosen the best response.2I would not say you are 100% correct. You are 50% correct. Remember \(A=b\) means \(a=b\) and \(a=b\) So you have \(6x=5\) which gives \(x=1\) But we must also consider \[(6x)=5\] which leads to \(x=11\).

Best ResponseYou've already chosen the best response.2But we are all actually wrong as it asked for the answer in set notation, so the answer is \(\{1,11\}\)

Best ResponseYou've already chosen the best response.0so the interval notation is from smallest to biggest ?

Best ResponseYou've already chosen the best response.2\[\left\{ 1,11 \right\}\]means that there r 2 elementary solutions 1 and 11 :)

Best ResponseYou've already chosen the best response.2when ever you see the modulus you have to consider the negative and positive values means less then the positive value and greater than the negative value like that \[\left x \right=4\] it means 4<x>4

Best ResponseYou've already chosen the best response.0oh okay . Got it !! Thank Yous !!! I have another equation bur under same category. l 4x2 l =11 x= 13/4 and x = 9/4 ? interval notation : { 9/4 , 13/4 }
