A method for solving a system of linear equations where you add or subtract the equations to eliminate a variable.
infinitely many solutions
The number of solutions of a system of equations in which the graphs of the equations are the same line.
A mathematical sentence that describes a region of the coordinate plane having a boundary line. Each point in the region is a solution of the inequality.
When the graphs of the equations in a system are parallel with no point of intersection.
solution of a system of linear equations
Any ordered pair in a system that makes all the equations of that system true.
solution of a system of linear inequalities
Any ordered pair that makes all of the inequalities in the system true.
solutions of an inequality
Any value or values of a variable in the inequality that makes an inequality true.
A method of solving a system of equations by replacing one variable with an equivalent expression containing the other variable.
system of linear equations
Two or more linear equations using the same variables.
system of linear inequalities
Two or more linear inequalities using the same variables.
