I'm going to assume that the equation is 
where the 't' is not in the denominator
If that assumption is correct, then we do two things to solve for t. First, we multiply both sides by 16. This undoes the division of 16 on the left side
-------------------------------
Then we divide both sides by 5 to undo the multiplication of 5 (note: 5t means 5*t or "5 times t")
-------------------------------
So here's what all the steps look like:
note: -144/5 converts to the decimal value of -28.8 so t = -144/5 is the same as t = -28.8
