Answer:
B
Step-by-step explanation:
So, we have the expression:
[tex](3k-1)-(5k-4)[/tex]
First, distribute the negative on the right:
[tex]=3k-1-5k+4[/tex]
Combine like terms:
[tex]=(3k-5k)+(-1+4)[/tex]
Add:
[tex]=-2k+3[/tex]
So, our only correct answer is B.
The other answers can't be obtained.
And we're done!
