Now that we have isolated x, we can plug this into our second equation for x: To do this, we need to divide both sides by 8: We can do this by isolating x on one side of the equal sign. It does not matter which one you choose, but let’s say we choose to solve the first equation for x in terms of y. Next, we need to choose which equation we are going to solve for a variable in terms of the other variable. In order to do this, we need to add 5x to both sides of the first equation and subtract 4x from both sides of the second equation. This means that we want all of our equations to be in slope-intercept form, which looks like y=mx+b. The first step in solving this system is to put it in standard form. The graphing method is when we graph each equation on a coordinate plane and find where they intersect. The substitution method is when we use one equation to solve for a variable in another equation. We will be using the substitution method and the graphing method to solve the system. We will be discussing the solution of a system of linear inequalities. Solution of a System of Linear Inequalities The solution to the system is the intersection of the half-planes (or regions) determined by each inequality that is, the solution is the region where all three inequalities are satisfied. To graph a system of linear inequalities, we graph each inequality on its own coordinate plane. This system has three linear inequalities in the variables x and y. For example, consider the following system of linear inequalities: Any point in these intersection areas will be a solution to your system! System of Linear Inequalities in Two Variables Examples With AnswersĪ system of linear inequalities in two variables is a set of two or more linear inequalities in the same variables. These intersections will be the solutions to your system of inequalities because they will be the values that make all of the inequalities true simultaneously. Once you have each inequality graphed, look for the areas where they intersect. Be sure to use different colors or symbols for each inequality so that you can easily tell them apart. The first step is to graph each inequality on its own coordinate plane.

Now that we’ve reviewed what a system of inequalities is, let’s talk about how to solve one using graphing. In order to solve a system of inequalities, we need to find the values that make all of the inequalities true. A system of inequalities is two or more linear equations that are not equal to each other. In this blog post, we’ll walk you through the steps of solving a system of inequalities by graphing.įirst, let’s review what a system of inequalities is. When it comes to solving a system of inequalities, graphing is often the most efficient method.

To use algebraic methods to solve a system of inequalities, you need to first rewrite each inequality in standard form. The solutions to the system will be the points that are common to all of the graphs. To use a graphing calculator to solve a system of inequalities, you first need to graph each inequality on the same coordinate plane. This can be done by using a graphing calculator or by using algebraic methods. To solve a system of inequalities algebraically, you must find the values of the variables that make all of the inequality statements true.

This involves adding or subtracting the equations so that one of the variables cancels outĬan You Solve a System of Inequalities AlgebraicallyĪ system of inequalities is a set of two or more inequality statements that relate two or more variables.

This involves solving one of the equations for one of the variables, and then plugging this value into the other equation.

There are a few different ways that you can solve a system of inequalities without graphing.
