## Problem Solving With Linear Equations

Keep in mind that projectile problems (like shooting an arrow up in the air or dropping a penny from the roof of a tall building) are also parabola problems, using: if you're working in feet).In problem solving it is good to look back (check and interpret)..Basically, check to see if you used all your information and that the answer makes sense.That rate will be Since the break-even point is when revenue = cost, we will go right into setting this up using the substitution method as discussed in Tutorial 19: Solving Systems of Linear Equations in Two Variables.Math works just like anything else, if you want to get good at it, then you need to practice it.Just as "26" is "10 times 2, plus 6 times 1", so also the two-digit number they've given me will be ten times the "tens" digit, plus one times the "units" digit.In other words: that make the quadratic equation true.As mentioned before, whether you like it or not, whether you are going to be a mother, father, teacher, computer programmer, scientist, researcher, business owner, coach, mathematician, manager, doctor, lawyer, banker (the list can go on and on), problem solving is everywhere.Some people think that you either can do it or you can't.The word problems in this section all involve setting up a system of linear equations to help solve the problem.Basically, we are combining the concepts from Tutorial 8: An Introduction to Problem Solving, Tutorial 19: Solving Systems of Linear Equations in Two Variables and Tutorial 20: Solving Systems of Linear Equations in Three Variables all rolled up into one tutorial.
