Context examples:
Losing is never an option to an Aries, and beginning March 19 the Sun will be in Aries, considered to be in exaltation meaning it is in the very best place for the Sun to be, allowing you to grow in leadership skills, so we have to add that to the equation, too.

Regression analysis provides a "best-fit" mathematical equation for the relationship between the dependent variable (response) and independent variable(s) (covariates).
(Parametric Regression Method, NCI Thesaurus)
In the case where mathematical or chemical objects contain arbitrary variables, such a requirement may mean finding those values of the variables that turn the equation into equality.
(Equation, NCI Thesaurus)
The way we represent the universe and its history are described by Einstein's equations of general relativity, Newton's universal gravitation and quantum mechanics.

Equations are sometimes called more explicitly as conditional equations.
(Equation, NCI Thesaurus)
The empty space plays a primordial role in Einstein's equations as it operates in a quantity known as a "cosmological constant", and the resulting universe model depends on it.
