To subtract 2(k-4)-3(2k-1), we need to distribute the coefficients in each term:
2(k-4) = 2k - 8
3(2k-1) = 6k - 3
Now we can substitute these values back into the original expression and simplify:
2(k-4) - 3(2k-1) = 2k - 8 - (6k - 3)
Next, simplify by distributing the negative sign to each term inside the parentheses:
2k - 8 - 6k + 3 = (2k - 6k) + (-8 + 3)
Combine like terms:
-4k - 5
So, the correct answer is -4k - 5.
