Linear Programming Linear Programming Solving systems of inequalities has an interesting application--it allows us to find the minimum and maximum values of quantities with multiple constraints. First, assign a variable x or y to each quantity that is being solved for. Write an equation for the quantity that is being maximized or minimized cost, profit, amount, etc. This is that maximization or minimization equation.

Due to the nature of the mathematics on this site it is best views in landscape mode. If your device is not in landscape mode many of the equations will run off the side of your device should be able to scroll to see them and some of the menu items will be cut off due to the narrow screen width.

Linear Systems with Two Variables A linear system of two equations with two variables is any system that can be written in the form.

Also, the system is called linear if the variables are only to the first power, are only in the numerator and there are no products of variables in any of the equations. Here is an example of a system with numbers. This is easy enough to check.

Do not worry about how we got these values. This will be the very first system that we solve when we get into examples.

Note that it is important that the pair of numbers satisfy both equations. Now, just what does a solution to a system of two equations represent? Well if you think about it both of the equations in the system are lines.

As you can see the solution to the system is the coordinates of the point where the two lines intersect. So, when solving linear systems with two variables we are really asking where the two lines will intersect.

We will be looking at two methods for solving systems in this section. The first method is called the method of substitution.

In this method we will solve one of the equations for one of the variables and substitute this into the other equation. This will yield one equation with one variable that we can solve. Once this is solved we substitute this value back into one of the equations to find the value of the remaining variable.

In words this method is not always very clear. Example 1 Solve each of the following systems. We already know the solution, but this will give us a chance to verify the values that we wrote down for the solution. Now, the method says that we need to solve one of the equations for one of the variables.

This means we should try to avoid fractions if at all possible. This is one of the more common mistakes students make in solving systems.The solution of a linear system is the ordered pair that is a solution to all equations in the system.

One way of solving a linear system is by graphing. The solution to the system will then be in the point in which the two equations intersect.

Write and graph a system of linear inequalities that GUIDED PRACTICE for Examples 3 and 4 Write a system of inequalities that defines the shaded region. 4. 5. 6. system has one solution, no solution, or infinitely many solutions.

Mathematically proficient students start by explaining to themselves the meaning of a problem and looking for entry points to its solution. Pearson Prentice Hall and our other respected imprints provide educational materials, technologies, assessments and related services across the secondary curriculum.

Graph – how much I make at the mall. In other words, when we graph the line, we can go over (back and forth) to see what the hours are and then look up to see how much we would make with that many hours.

You can think of the \(x\) as the “question” on the bottom where you go back and forth, and then look up and down to get the “answer” where the \(y\) is – the answers are all on. A "system" of inequalities is a set of inequalities, usually two or three, that you deal with all at once.

The solution to the system of inequalities is simply the intersection of the solutions for each of the individual parts.
