Answer

k + 2\text{k + 2}

Step-by-step solution

4 steps

  1. Start with the input, which is kk.

    kk

  2. Apply the first operation, which is to add 5.

    k+5k + 5

  3. Apply the second operation, which is to subtract 3 from the previous result.

    (k+5)−3(k + 5) - 3

  4. Simplify the expression.

    k+5−3=k+2k + 5 - 3 = k + 2

    The output is k + 2\text{k + 2}.
