use the properties of operations to subtract (h + k) - (2k - h)

To subtract (h + k) - (2k - h), we distribute the negative sign to the second term inside the parentheses:

(h + k) - (2k - h) = h + k - 2k + h

Next, combine the like terms:

(h + k) - (2k - h) = (h + h) + (k - 2k)

Simplify further:

(h + k) - (2k - h) = 2h + (-k)

Finally, we can write the answer as:

(h + k) - (2k - h) = 2h - k
