- Video 1 -Solving Linear Equations and Linear Inequalities.
- Solving Linear Equations.
This segment covers the solution of linear equations, balancing equations, isolation of the unknown, and moving terms from one side of the equation to the other. Removal of parentheses and simplification of terms is covered as well as collecting like terms. Equations covered are at the intermediate algebra level of difficulty. Also covered are literal equations or equations involving several different symbols in which one in particular is to be isolated.
- Applications that Lead to Linear Equations.
This segment covers a variety of intermediate level word problems including problems involving distance, speed, and time as well as problems involving interest rates.
- Solving Linear Inequalities.
This segment covers solving linear inequalities by isolating the unknown using methods similar to those for linear equations. The reversal of inequality symbol when multiplying both sides of an inequality by a negative number is also covered. The problems covered here are at the intermediate algebra level of difficulty.
- Solving Absolute Value Equations.
This segment covers the solution of equations in which one or more terms contain the absolute value of a linear expression in the unknown . The method of isolation of the absolute value term is used.
