1) The document discusses using the distributive property to solve linear equations and discusses how not all linear equations have solutions. It provides examples of using the distributive property to both simplify and expand expressions. 2) The distributive property is applied only to terms within a group and not to terms outside of the group. An equation has no solution if it can be transformed into an untrue statement when solving. 3) The document concludes by reminding students how to use the distributive property to transform equations and that some equations have no solutions. It provides recommendations for additional practice on IXL.
