The equation most widely used is called the Gordon growth model.

If no such values can satisfy all of the equations in the system, then the equations are called "inconsistent."

This equation is sometimes called the first structure equation.

This equation and the preceding one are called metric equations.

In consumer theory, the equation restricting an individual or household to spend no more than its total resources is often called the budget constraint.

The larger equation is called a mixed economy, and that is what we are constructing here.

The professor's own questionable equation here might be called guilt by assumption.

For this reason this equation is also called the constant selectivity relationship.

Two equations are called equivalent if they have the same set of solutions.

This model or equation will be called a synthesizer build.
