Answer:
Constitutional Monarchies
Representative Democracies
Explanation:
In both forms of government, citizens have a say in either the election process of officials (Representative Democracy), and then another gives citizens a say in what is written in their constitution (Constitutional Monarchies)
A representative democracy exercises the idea of the governed choosing elected officials to make decisions on their behalf.
A constitutional monarchy supports the idea that a government body helps the monarch decide what is to be written on their constitution.
As explained, both support the idea of electing certain people/officials to make decisions on their behalf.
