To subtract the expression \((h + k)\) from \((2k - h)\), we can rewrite the expression as follows:
\[ (h + k) - (2k - h) \]
Next, we'll distribute the negative sign across the second expression:
\[ (h + k) - 2k + h \]
Now, we can combine like terms. First, let's combine the \(h\) terms:
\[ h + h = 2h \]
Next, we combine the \(k\) terms:
\[ k - 2k = -k \]
Putting it all together, the expression simplifies to:
\[ 2h - k \]
Thus, the result of the subtraction \((h + k) - (2k - h)\) is:
\[ 2h - k \]
