The graph of a linear equation in three variables is a plane in three – dimensional space. The graphs of three equations that form a system are three planes whose intersection determines the number of solutions of the system, as shown in the picture below. The above images are examples of systems of equations in 3 unknowns with No Solutions. All three planes never meet at a single point or
Section 7-2 : Linear Systems with Three Variables. This is going to be a fairly short section in the sense that it’s really only going to consist of a couple of examples to illustrate how to take the methods from the previous section and use them to solve a linear system with three equations and three variables.
When solving systems of equation with three variables we use the elimination method or the substitution method to make a system of two equations in two variables. Example Solve the systems of equations (this example is also shown in our video lesson)

than two variables. For example, a linear equation in three variables represents a plane in three-dimensional space. In this chapter, we see how some real-world problems can be formulated in terms of systems of linear equations, and we also develop two methods for solving these equations. In addition, we see how matrices (rectangular arrays of numbers) can be used to write systems of linear
So far, our efforts have reduced the system from three variables in three equations to two variables in two equations. Now, we can apply the substitution technique again to the two equations 4y – z = 4 and -3y + 4z = 36 to solve for either y or z .

From Lesson 3.5 you know that the graph of a linear equation in three variables is a plane. Three planes in space can intersect in different ways. If the planes intersect in a single point, If the planes intersect in a line, as as shown below, the system has exactly shown below, the system has one solution. infinitely many solutions. If the planes have no point of intersection, the system has
The second equation must be multiplied by 3 in order to get 15 in front of x. Now subtract the second equation from the first equation to get the following: At this point, you can either replace y with and solve for x (method 1 that follows), or start with the original two equations and eliminate y in order to solve for x (method 2 that follows).

The second equation must be multiplied by 3 in order to get 15 in front of x. Now subtract the second equation from the first equation to get the following: At this point, you can either replace y with and solve for x (method 1 that follows), or start with the original two equations and eliminate y in order to solve for x (method 2 that follows).

From the two simultaneous equations, it appears that the formation of relation (A) by cross-multiplication is the most important concept. At first, express the co-efficient of the two equations as in the following form: Now multiply the co-efficient according to the arrow heads and subtract the upward product from the downward product. Place the three differences under x, y and 1 respectively
