Question 239530
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the number.  Then the sum of a number an seven is: *[tex \Large x\ +\ 7].  Three times that is *[tex \Large 3(x\ +\ 7)].  Five times the number is *[tex \Large 5x], and less thirteen is then *[tex \Large 5x\ -\ 13].


Put it all together:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 3(x\ +\ 7)\ >\ 5x\ -\ 13]


Solve for the solution set interval.  Remember to reverse the sense of the inequality if you multiply by a negative value.
