Step-by-step explanation:
The process through which the constitution can be altered is called amendment. This is the formal process established in the Constitution, wherein an amendment must first be proposed by a two-thirds vote in both houses of Congress or by two-thirds of all state legislatures. It must then be ratified by three-fourths of the state legislatures. This process has been used 27 times in American history to amend the Constitution.
