A method for solving a linear system with no solution is described. The method is described in 4 steps. The first step in the method is designed to solve a linear system that is described consist of “solving by graphing”. Details for “solving by graphing” first consist of finding points to graph using two different equations. The second step in the method consist of placing the points from both equations on the same graph in order to find out if bo...

Solving 6 math problems using different methods is the idea behind this video. First, you make three rows of numbers vertically from 1-9. All the numbers match across for example, 1 1 1, 2 2 2, 3 3 3, and so on. Each set of numbers creates a mathematical problem who's solution is the number six. These problems require some thinking to solve. The only one that is immediately apparent is 2 2 2=6 which is, of course, 2+2+2=6, (3x3)-3=6, the square root of 4 =2. This done on all three of the four...

Given a equation of a line, you can graph the line. A system of equations is nothing but equations of more than one line. In a single equation all the points that lie on the line, satisfy the equation of the line. Similarly a solution of a system of equations is points that satisfy each and every equation of that system. A system of equations can have a single point as solution when the lines intersect at a common point, or have a unlimited points in solution when the lines overlap on each ot...

In this video the instructor shows how to solve a system of equations by elimination method. First you need to know how many possible number of solutions you can get by solving a system of equations. There are three possibilities. In the first case there are two lines with different slopes, so they intersect at a point which is the solution to that system. In second case there can be two lines with same slope but are parallel to each other. In this case the system has no solution. In the thir...

Want to test whether the soil sample or a water sample contains boron, watch this video. As shown in the video, the first step is to create test specimens of various concentrations using a simple turmeric and ethanol solution as a base for comparison. The basis of this experiment is the fact that curumin present in turmeric reacts with boron to form a reddish compound and so the result of this reaction can easily be verified visually.
