Simplify -3/4r + 3 - 5/6r -6
To simplify the given expression -3/4r + 3 - 5/6r - 6, we can combine like terms:
-3/4r - 5/6r + 3 - 6
To combine the terms with r, we need a common denominator for 4 and 6, which is 12. So we will multiply -3/4r by 3/3 and -5/6r by 2/2:
(-9/12r) + (-10/12r) + 3 - 6
Now we can combine the terms with r:
(-9/12r) + (-10/12r) = (-19/12r)
Therefore, the simplified expression is:
(-19/12r) + 3 - 6
Next, combine the constants:
(-19/12r) + 3 - 6 = (-19/12r) - 3
Hence, the simplified expression is -19/12r - 3.
