Answer:
the answer should be 9 1 /3 for the value of t because first of all you need to do the following steps.
_t+1__= 2 7/12
4
_t+1__= 31/12
4
then you multiplied it by 4 each side getting an answer of for this step
t+1= 31/3
then you need to subtract 1 from each side because if its add then the opposite of its subtract.
==> t+1-1= 31/3 -1
===> t= 28/3 and you simplified it as 9 1/3 so that is the correct and have a great day.
