Question 225414
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the number.  Then the difference between that value and twelve is *[tex \Large x - 12].  Six times that difference is *[tex \Large 6(x - 12)].  One half of the number is *[tex \Large \frac{x}{2}], so:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 6(x - 12)\ =\ \frac{x}{2}]
