Exploring Solutions in Systems of Linear Equations

This video tutorial explains linear systems and their solutions, including one solution, no solution, and infinitely many solutions. It provides examples and graphing techniques to illustrate each type of solution. The tutorial also includes algebraic verification of solutions and concludes with a social media promotion.

How can we verify the solution of a linear system algebraically?

• By multiplying the equations

• By substituting the solution into the equations

• By adding the equations

• By graphing the equations

What is the result of substituting the solution into both equations of a system with one solution?

• No outcome

• The same outcome for both equations

• An undefined outcome

• Different outcomes for each equation
