Answer:
t=2
Explanation:
We have the equation:

And the main thing here is if we do one thing to an equation we do it to both sides. So if we subtract 1/4 from one side, we do it to both sides. If we subtract 1/4 from the left side it cancels out with the 1/4 leaving us just with the "t" unknown, giving us a solution:

Now from here we can just multiply the 1/4 by 3/3 so we get the same denominator and combine them into one fraction:

Now subtract the numerators:

Simplify:
t=2
