subtract 2(k-4)-3(2k-1)

-4k-5
8k-11
-4k-11
-6k-18

To subtract 2(k-4)-3(2k-1), we need to distribute the 2 and the 3:

2(k-4) = 2k - 8
-3(2k-1) = -6k +3

Now, we can subtract these two expressions:

2k - 8 - 6k + 3

Combine like terms:

(2k - 6k) + (-8 + 3)

-4k - 5

So, the simplified expression is -4k - 5.
