How do you solve 13 1/4- t= 3 5/6? Could you give me a step-by-step walkthrough? Thank you!?

53/4 - t = 23/6
159 - 12 t = 46
113 = 12 t
t = 113 / 12

13 1/4 - t = 3 5/6
t = 13 1/4 - 3 5/6
t = 13 3/12 - 3 10/12
t = 12 15/12 - 3 10/12
t = 9 5/12

The first thing you should do is change those mixed numbers into improper fractions. That gives you:
53/4 - t = 23/6

Find the common denominator:

159/12 - t = 46/12

Add t to both sides (I like to move the variable to make it a positive number):
159/12 = 46/12 + t

Get t by itself:
159/12 - 46/12 = t
113/12 = t

Change back to a mixed number if you wish:
9 5/12 = t

13 1/4- t= 3 5/6
+t -3 5/6 = +t -3 5/6
13 1/4 - 3 5/6 = t
Change your fractions into 1/12.
