Use the properties of operations to subtract (h + k) - (2k - h).
Options:
2h + k
-2h -k
-k
2h -k
We can distribute the negative sign to the terms inside the second parentheses since subtraction is the same as adding the opposite.
(h + k) - (2k - h)
= h + k - 2k + h [Distribute the negative sign]
= (h + h) + (k - 2k) [Combine like terms]
= 2h - k [Simplify]
Therefore, the answer is 2h - k.
