IN COLLECTION

This unit discusses systems of linear equations and their solutions.

This video shows how one can solve a system of linear equations by carefully graphing them and seeing where the lines intersect.

This video shows an algebraic technique for solving systems of equations. One solves for one variable and substitutes it into the second equation.

This video shows a second algebraic technique for solving systems of equations: elimination. One works to eliminate one variable by combining two equations. In all these examples, the elimination requires but a single step.

This video extends the technique of elimination to include more complicated problems requiring multiplication.

This video classifies systems of linear equations by whether they are consistent (unique solution), dependent (multiple solutions), or inconsistent (no solutions).

This video tackles the problem of systems of simultaneous inequalities. Their solution can be shown graphically or algebraically.
