Question 261894
<font face="Garamond" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 9d\ +\ 7e]


where


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ d\ =\ -2]


and


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ e\ =\ 4]


Just plug in the values and do the arithmetic:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 9(-2)\ +\ 7(4)]


I'll leave the arithmetic to you.
