Plus model problems explained step by step Agency C charges \\$0.50 for each mile you drive. Graphing a system of equations shows students the most visual representation. “Systems of equations” just means that we are dealing with more than one equation and variable. In this project, you will be planning - and budgeting - for that future. In this project, you will be planning - and budgeting - for that future. Solving Systems of Linear Equations A system of linear equations is just a set of two or more linear equations. You need to decide which agency to rent a car from. In this method he isolates either the x or y variables in both the equations and now compares the other side of equations directly to derive the value of the other variable. You will then create a budget for one-month's worth of spending in your future life.
