Algebra 1 - Defining Equations & their Solutions

In this lesson I introduce and define Equations, how to determine if an equation is an Open Equation or a Closed Equation, and whether or not an equation is True. Examples 1-3 are at 2:36 5:26 7:16 We then work though three examples where we test whether given values are solutions to the given equations at 14:31 17:11 23:13 Now that we know how to check if a value is a solution, lets use a t-table to help find our own solutions, examples at 25:02 27:13 Finally at 31:35 we use mental math to find solutions to 4 Single Step Equations.
