7+3t -t
------- = ----- is the relevant equation here. We don't ask, "What is 7+3t over
4 8 -t over 8," but rather "Solve the following equation for t."

Cross multiplying, 56 + 24t = -4t

-56
Then: 28t = 56, and t = ------ = -2 (answer)
28

The solution to "What is 7+3t over 4 = -t over 8" is t = -2.
