simplyfly - 3/4 r + 3 - 5/6 r -6
To simplify the expression, first combine like terms:
(3/4r - 5/6r) + (3 - 6)
To combine the terms with r, find a common denominator of 4 and 6, which is 12.
(9/12r - 10/12r) + (9/12 - 72/12)
Combine the terms with r:
(-1/12r) + (-63/12)
To simplify further, combine the constants:
-1/12r - 63/12
Now, you can simplify the rational expression:
(-1r - 63)/12
