Unformatted text preview: When you solve the equation by looking at the data table, the solution is the x-value when the y-values for both equations are the same. When and are both 3, X is 2. (That is where the lines intersect in the graphical solution.) Any of these approaches gives you the same answer. ***A final note for this topic: You may find one approach to solving equations works well for you. However, as you continue your study of algebra there will be problems that are more easily solved by using a graph or setting up a table. Therefore, you should practice all three methods and understand how each gives the solution to the equation. As you gain more practice solving equations you will have tools to determine the best strategy for when to: solve by hand (analytically). solve with a graph. solve using a table....
