Answer 1

In mathematics, an equation is a statement that asserts the equality of two expressions, which are connected by the equals sign "=".[2][3][4] The word equation and its cognates in other languages may have subtly different meanings; for example, in French an équation is defined as containing one or more variables, while in English, any equality is an equation.[5]
