In our last lesson we used the Linear Combinations or Addition Method to solve words of equations. Now we are ready to apply these strategies to solve real world problems. Are you ready. First let's look at some guidelines for solving real world problems and then we'll look at how few examples. Steps For Solving Real World Problems Highlight the personal statement in the problem that will help write two equations. Define your variables Use one of the methods for solving systems of equations to solve. Check your answers by substituting your ordered pair into the original equations. For example, given coordinates for two pairs of points, determine equation the line through the first pair of points intersects the line through the second pair. Common Core: 8. I can describe the solve s of Call for papers 2013 human resource management between two lines as the points that satisfy both equations simultaneously. I can define "inspection.
