equation = equate (transparent) = equate + ion

Formed by the verb 'equate' plus the nominalizing suffix '-ion'; the noun's mathematical sense follows the standard pattern and is inferable from the verb.

Etymology

The word equation comes from the old Latin root aequ- meaning 'equal', the same root as the common word equal. In math, an equation is a statement that shows two sides are 'equal', so the origin explains the meaning.
