Systems of Two Equations: Substitution Method

Systems of Two Equations: Substitution Method

This is the second topic in the Systems of Two Equations section of the series of lessons on math provided by DeafTEC. Gary Blatto-Vallee, a math and science instructor at the National Technical Institute for the Deaf, guides viewers through a variety of mathematical exercises in this DeafTEC video series. All lessons are fully captioned, signed in ASL, and voiced. In this section, four videos are included that show students examples of solving systems of two equations with the substitution method both with consistent and inconsistent equations. At the end of this section, problems are included for students to check their understanding. See the main Math Video Resources page for an introduction to this video series.
