Solving Linear Systems by Graphing
by Sal KhanThis video shows how one can solve a system of linear equations by carefully graphing them and seeing where the lines intersect.
Solving Linear Systems by Substitution
by Sal KhanThis video shows an algebraic technique for solving systems of equations. One solves for one variable and substitutes it into the second equation.
Solving Systems of Equations by Elimination
by Sal KhanThis 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.
Special Types of Linear Systems
by Sal KhanThis video classifies systems of linear equations by whether they are consistent (unique solution), dependent (multiple solutions), or inconsistent (no solutions).
Systems of Linear Inequalities
by Sal KhanThis video tackles the problem of systems of simultaneous inequalities. Their solution can be shown graphically or algebraically.
