Best ResponseYou've already chosen the best response.0You solve it like you would a normal equation, the only difference is when you try to divide to get x by itself. If you divide by a negative number you flip the "<" to a ">"

Best ResponseYou've already chosen the best response.0\[2x3<7\] \[2x<10\] \[x = \frac{ 10 }{ 2 }\] \[x = 5\]

Best ResponseYou've already chosen the best response.0To what I said earlier, if it was: 2x < 10 In order to solve for x you would have to divide by 'negative' 2. Since you divide by a negative you just flip the sign to a >

Best ResponseYou've already chosen the best response.0Oh it's an absolute value? Ok it's going to be a little different

Best ResponseYou've already chosen the best response.0Ok, first you have to get the absolute value by it self, in this chance it already is. Now, you need to have 2 equations. One is set equal to 7, and the other equal to 7 so, \[2x3 < 7\] and \[2x3<7\]

Best ResponseYou've already chosen the best response.0Then you just solve both of them like I did earlier. You'll get 2 values, one from each equation. Make sense?

Best ResponseYou've already chosen the best response.0First you add 3 to both sides so that you get : 2x = 10. Now divide both sides by 2 and what do you get?
