Answer
Explanation
Given:
5k+(−2k)−(−1)
To simplify the above given, we first apply the rule:
[tex]a+(-b)=a-b[/tex]So,
[tex]5k+(-2k)-(-1)=5k-2k-(-1)[/tex]Next, we apply the rule:
[tex]a-(-b)=a+b[/tex]Hence,
[tex]5k-2k-(-1)=5k-2k+1[/tex]Then, we simplify:
[tex]5k-2k+1=3k+1[/tex]Therefore, the answer is:
[tex]\begin{equation*} 3k+1 \end{equation*}[/tex]
