Answer:

Step-by-step explanation:
3t − 1/4 = 7/8
Add 1/4 to both sides.
3t + −1/4 + 1/4 = 7/8 + 1/4
3t = 9/8
Divide both sides by 3.
3t/3 = 98/3
t=3/8
Answer:

Step-by-step explanation:
Split it up like this to make it easier to work with:

Since the only thing in the denominator of those fractions is a 3, we can only divide the 27 by 3, not the x or y terms. Same thing with the second fraction. 27 divided by 3 is 9 and 15 divided by 3 is 5, so

is the solution. It is not completely simplified, but that isn't what you asked for, so this should suffice as the answer.
3-y?
-y=-3
cancel minus both side
y=3
