Question 191702
<font face="Garamond" size="+2">


Multiply both sides by 4


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 4 \frac{t}{4} = 5\,\cdot\,4]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ t = 20]


This should make sense if you say to yourself: "If I divide something by 4 and get 5, what must that something have been?"
