1) The document provides instructions and examples for solving equations. It begins with assigning practice problems from the textbook and reminds students to sign tests. 2) The next section provides tips for solving equations, such as combining like terms and using addition or subtraction properties of equality. 3) Examples of solving different types of equations are shown, along with checking the solutions. 4) One example asks students to find the value of x so that two shapes have the same perimeter.

Lesson 2.4:
FYI...
*To solve an equation that has variables on each side of the equals sign, "move" the variable
terms so that they are all on one side.
*To "move" them ­ use the addition or subtraction property of equality
*When you move them to the new side...combine them with any other like terms.
*Also, remember to "simplify" before moving anything!
*.... 15 = 15 .... this is an "Identity" type of equation (all real #'s)
*.... 15 = 17 .... this is a "no solution" type of equation
