Answer

Step-by-step explanation

Given:

5k+(−2k)−(−1)

To simplify the above given, we first apply the rule:


a+(-b)=a-b

So,


5k+(-2k)-(-1)=5k-2k-(-1)

Next, we apply the rule:


a-(-b)=a+b

Hence,


5k-2k-(-1)=5k-2k+1

Then, we simplify:


5k-2k+1=3k+1

Therefore, the answer is:


\begin{equation*} 3k+1 \end{equation*}
