Subtract 2 (k - 4) - 3 (2k - 1).
To subtract 2(k - 4) - 3(2k - 1), we need to distribute the factors first.
2(k - 4) becomes 2k - 8.
3(2k - 1) becomes 6k - 3.
So the expression becomes:
2k - 8 - (6k - 3).
To subtract the expression inside the parentheses, we can distribute the negative sign:
2k - 8 - 6k + 3.
Combining like terms, we have:
(-4k) + (-5).
Simplifying further, we get:
-4k - 5.
