___________________ is a method of solving a system of two equations in two variables where you add or subtract a multiple of one equation to another in order to get an equation with only one of the variables.

Two systems are called ___________________ if they share the exact same solution set.

A ___________________ is a mathematical or statistical representation of a problem from science, technology, engineering, work, or everyday life, used to solve problems and make decisions

Two or more equations that represent the constraints in the same situation form a ___________________.

___________________ is replacing a variable with an expression it is equal to.

A ___________________ is a limitation on the possible values of variables in a model, often expressed by an equation or inequality or by specifying that the value must be an integer.

Two or more inequalities that represent the constraints in the same situation form a ___________________.

The ___________________ can be represented by the points in the region where the graphs of the two inequalities overlap.

Equations that have the exact same solutions are ___________________.

A coordinate pair that makes both equations in the system true is called a ___________________.
