semplify - 3/4r +3 - 5/6r - 6
To simplify the expression -3/4r + 3 - 5/6r - 6, combine like terms.
First, combine the coefficients of r:
-3/4r - 5/6r
To combine these fractions, we need to find a common denominator. The common denominator of 4 and 6 is 12.
-3/4r = -9/12r
-5/6r = -10/12r
Now, simplify:
-9/12r - 10/12r
Combine the fractions:
(-9 - 10)/12r
Perform the operation in the numerator:
-19/12r
Finally, combine the constants:
-19/12r + 3 - 6
Combine:
-19/12r - 3
So, the simplified expression is -19/12r - 3.
