To solve this expression, we can distribute the coefficients to each term within the parentheses.
First, distribute 9 to (k + 1/3):
9(k + 1/3) = 9k + 9(1/3) = 9k + 3
Next, distribute 10 to (1/2k - 1):
10(1/2k - 1) = 10(1/2k) + 10(-1) = 5k - 10
Now, we can add the two simplified expressions together:
(9k + 3) + (5k - 10)
Combining like terms, we get:
9k + 5k + 3 - 10
Simplifying further:
14k - 7
Therefore, 9 (k + 1/3) + 10 (1/2k - 1) simplifies to 14k - 7.
