Question 321751
<font face="Garamond" size="+2">


Let *[tex \Large x] represent the number of trips made by the larger truck.  Then the number of tons delivered by the larger truck must be *[tex \Large 4x].  The number of trips made by the smaller truck is *[tex \Large x\ +\ 18] and the number of tons delivered by the smaller truck is *[tex \Large 3(x\ +\ 18)].  Since this is 12 more tons than was delivered by the larger truck:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 3(x\ +\ 18)\ =\ 4x\ +\ 12]


Solve for *[tex \Large x]
