Master solving a system of equations by substitution with no solution and infinite many

The video tutorial explains how to solve systems of equations using substitution, focusing on cases with no solutions and infinite solutions. It covers identifying variables with coefficients of 1 or -1 for substitution, solving algebraically, and understanding the graphical representation of solutions. The tutorial demonstrates solving systems with no solutions, where lines are parallel, and systems with infinite solutions, where lines overlap.

In your own words, explain the difference between a system of equations with infinite solutions and one with no solutions.

What is the outcome when you simplify an equation and arrive at a true statement?

How can you verify that two equations have infinite solutions?
